How to File a Consumer Complaint with DTI
The Department of Trade and Industry (DTI) is the primary government agency mandated to protect consumers in the Philippines. Under Republic Act No. 7394, also known as the Consumer Act of the Philippines, the DTI has the authority to receive, investigate, and resolve complaints from consumers who have been subjected to deceptive, unfair, or unconscionable business practices. Whether you purchased a defective product, were misled by false advertising, or experienced warranty violations, DTI provides a free and accessible mechanism for consumers to seek redress. This comprehensive guide explains the entire complaint filing process, the documents you need, what to expect during mediation, and how to follow through until your complaint is resolved.

What DTI Handles
DTI has jurisdiction over a wide range of consumer protection issues under RA 7394 and related laws. If your complaint involves any of the following, DTI is the correct agency to approach:
Product Quality Complaints
Defective or substandard products that do not meet the quality or safety standards declared on the label or implied by the seller. This includes electronics, appliances, clothing, food products, cosmetics, and other consumer goods sold in the Philippine market.
Price Act Violations
Overpricing, profiteering, hoarding, or price manipulation of basic necessities and prime commodities as defined under RA 7581 (Price Act). This includes unreasonable price increases during emergencies, calamities, or state-declared price freeze periods.
Deceptive & Unfair Sales Practices
Bait-and-switch tactics, false claims about product features or origin, hidden charges, unauthorized billing, refusal to honor promotional offers, and other unconscionable sales acts or practices intended to mislead or take advantage of consumers.
Warranty Issues
Refusal by a seller or manufacturer to honor product warranties, whether express (stated in writing or verbally) or implied (the legal warranty that a product is fit for its intended purpose). This includes failure to repair, replace, or refund defective products within the warranty period.
Product Safety Concerns
Products that pose a risk to consumer health or safety, including items that lack proper safety markings (such as the PS Mark or ICC Mark), products that have been recalled but are still being sold, or items that do not comply with mandatory Philippine standards.
Misleading Advertisements
False, misleading, or exaggerated claims in advertisements -- whether on television, radio, print, social media, or online platforms. This includes fake testimonials, misleading product photos, false endorsements, and advertisements that omit material information about a product or service.
Weight and Measure Violations
Short-weighing, use of tampered or uncalibrated weighing scales, selling products with inaccurate net weight or volume declarations, and other violations of the Weights and Measures Law. DTI regularly inspects markets, grocery stores, gas stations, and other retail establishments for compliance with standard weights and measures.
What DTI Does NOT Handle
DTI's consumer protection jurisdiction has limits. If your complaint falls outside DTI's mandate, you will need to approach the appropriate government agency. Here are common complaints that DTI does not handle:
Employment disputes (wages, illegal dismissal, labor standards) -- go to the Department of Labor and Employment (DOLE)
Banking and financial issues (ATM fraud, credit card disputes, loan issues) -- go to the Bangko Sentral ng Pilipinas (BSP)
Telecommunications complaints (internet service, mobile signal, billing) -- go to the National Telecommunications Commission (NTC)
Insurance complaints (claims denial, policy disputes) -- go to the Insurance Commission (IC)
Real estate complaints (subdivision/ condominium issues, developer disputes, housing complaints) -- go to the Department of Human Settlements and Urban Development (DHSUD), formerly known as HLURB
Requirements for Filing a Consumer Complaint
Before visiting a DTI office or filing online, make sure you have the following documents and evidence ready. Having complete documentation will speed up the processing of your complaint and strengthen your case during mediation.
| Requirement | Details |
|---|---|
| Complaint Letter or Sworn Affidavit | A written account of your complaint detailing what happened, when it happened, the product or service involved, the name and address of the seller or business, and the specific relief you are seeking (refund, replacement, repair, or damages). If filing a formal complaint, a sworn affidavit may be required. DTI offices provide complaint forms that you can fill out on-site. |
| Valid Government-Issued ID | At least one valid ID with photo and signature (e.g., Philippine passport, driver's license, PhilSys National ID, SSS ID, UMID, voter's ID, postal ID, or PRC ID). Bring the original and a photocopy. This is needed to verify your identity as the complainant. |
| Proof of Purchase | Official receipts, sales invoices, order confirmation emails, online transaction screenshots, delivery receipts, or any document that proves you purchased the product or service from the respondent business. This is one of the most important pieces of evidence in a consumer complaint. |
| Photos or Videos of Defective Product | Clear photographs or video recordings showing the defect, damage, or issue with the product. Include photos of the product label, packaging, serial number, and the specific defect. For misleading advertisements, include screenshots of the ad in question. Visual evidence greatly strengthens your case. |
| Copies of Warranty Card | If your complaint involves a warranty claim, bring the original warranty card or certificate and a photocopy. This should show the warranty period, terms, and conditions. Even if the warranty card has expired, bring it anyway as it may still be relevant to your complaint. |
| Correspondence with the Seller | Copies of any communication you have had with the seller or business regarding the issue -- including text messages, emails, chat logs, social media messages, or written letters. These show that you attempted to resolve the issue directly with the business before escalating to DTI, which demonstrates good faith on your part. |
Step-by-Step: How to File a Consumer Complaint
The following steps outline the complete process for filing a consumer complaint with DTI, from gathering your evidence all the way through to the enforcement of a decision. The entire process is free of charge.
Gather Your Evidence and Documentation
Before filing your complaint, collect all relevant evidence. This includes your receipt or proof of purchase, the defective product itself (if applicable), photographs or videos of the defect, your warranty card, and any correspondence with the seller (text messages, emails, chat logs). The stronger your documentation, the better your chances of a favorable resolution. Organize your documents chronologically so you can present a clear timeline of events.
Tip: If you purchased the product online, take screenshots of the product listing, the order confirmation, payment confirmation, and any promotional claims made by the seller. These are important evidence for online transaction complaints.
Prepare Your Complaint Letter
Write a clear and detailed complaint letter addressed to the DTI. Your letter should include: (a) your full name, address, and contact number; (b) the name and address of the business or seller you are complaining against; (c) a detailed narration of what happened, including dates and amounts; (d) what product or service is involved; and (e) the specific relief you are requesting -- whether it is a refund, replacement, repair, or compensation for damages. Be factual, specific, and avoid emotional language.
Note: If you visit a DTI office in person, complaint forms are available on-site. A DTI staff member can assist you in filling out the form if needed. You do not necessarily need to prepare a formal letter in advance, but having one ready will save time.
Visit a DTI Office or File Online
You have several options for filing your complaint: (a) Visit the nearest DTI provincial or regional office in person; (b) Go to a Negosyo Center in your city or municipality; (c) File online through the DTI Consumer Complaints Portal; or (d) Call the 1-DTI (1-384) hotline to report your complaint by phone. Walk-in filing is available Monday to Friday, 8:00 AM to 5:00 PM. Bring all your documents and evidence.
Tip: If you are unsure which DTI office has jurisdiction, file at the DTI office nearest to the location of the business you are complaining against, or the DTI office in the province or city where the transaction took place.
Submit Your Complaint and Receive a Reference Number
Upon submission of your complaint letter and supporting documents, the DTI officer will review them for completeness. If everything is in order, your complaint will be officially recorded and you will be given a complaint reference number. Keep this number safe -- you will use it to track the status of your complaint. The DTI will then send a notice to the business or seller (the respondent) informing them of the complaint and summoning them to a mediation conference.
Mediation / Conciliation Conference
DTI will schedule a mediation or conciliation conference within 15 working days from the date of filing. Both the complainant (you) and the respondent (the business) are required to attend. A trained DTI mediator will facilitate the discussion, helping both parties reach an amicable settlement. During mediation, the mediator will listen to both sides, review the evidence, and explore possible solutions such as a refund, product replacement, repair, or other forms of compensation.
Important: If a settlement is reached, both parties will sign a mediation agreement that is binding and enforceable. If the respondent fails to comply with the agreement, you can file a motion for execution with DTI.
Adjudication (If Mediation Fails)
If the mediation conference fails to produce a settlement -- because one or both parties cannot agree on a resolution -- the case will be elevated to formal adjudication. The complaint will be referred to a DTI Adjudication Officer who will conduct a formal hearing, evaluate the evidence, and issue a legally binding decision. Both parties may present additional evidence and witnesses during adjudication. The adjudication process typically takes 30 to 90 days, depending on the complexity of the case.
Enforcement of Decision
Once a decision is issued (either through a mediation agreement or an adjudication order), the respondent business is legally required to comply. If the business fails to comply with the DTI decision, the DTI can impose administrative fines and penalties, revoke business permits, or refer the case for criminal prosecution under RA 7394. The consumer may also seek enforcement through the regular courts. If the respondent wishes to appeal, they may file an appeal with the DTI Secretary or the Office of the President within the prescribed period.
Note: Decisions of the DTI Adjudication Officer may be appealed to the DTI Secretary within 15 days from receipt of the decision. Decisions of the DTI Secretary may be further appealed to the Office of the President or the Court of Appeals, as provided by law.
Online Filing via DTI Consumer Complaints Portal
For consumers who prefer the convenience of filing from home, DTI offers an online complaints portal. This is especially useful for consumers in remote areas or those who cannot personally visit a DTI office. Here is how to file online:
Visit the DTI Website
Go to the official DTI website at www.dti.gov.ph and navigate to the Consumer Protection section. Look for the "File a Complaint" or "Consumer Complaints" link. You may also access the complaints portal directly through the DTI e-Services page.
Fill Out the Online Complaint Form
Complete the online complaint form with your personal details (name, address, contact number, email), the details of the business or seller you are complaining against, a detailed description of your complaint, and the relief you are requesting. Make sure all information is accurate and complete.
Upload Supporting Documents
Attach digital copies of your supporting documents -- scanned receipts, photos of the defective product, screenshots of online transactions, warranty cards, and correspondence with the seller. Most common file formats are accepted (JPEG, PNG, PDF). Make sure your files are clear and legible.
Submit and Track Your Complaint
After reviewing your information, click "Submit." You will receive a confirmation email with your complaint reference number. Use this reference number to track the status of your complaint online or when calling the 1-DTI hotline. A DTI officer will contact you within a few working days to acknowledge receipt and discuss the next steps, including scheduling the mediation conference.
The DTI Mediation Process
Mediation is the primary method DTI uses to resolve consumer complaints. It is a voluntary, confidential, and non-adversarial process where a neutral DTI mediator facilitates a discussion between the consumer and the business to reach a mutually acceptable resolution. Here is what you need to know:
How Mediation Works
- Both parties are summoned to a face-to-face conference at the DTI office (or via video conference, when applicable)
- A trained DTI mediator facilitates the discussion in a neutral and impartial manner
- Each party presents their side and the supporting evidence
- The mediator helps identify the issues, clarify misunderstandings, and explore settlement options
- The goal is to reach a win-win resolution that both parties find acceptable
Possible Outcomes
- Full refund of the purchase price to the consumer
- Product replacement with a brand-new unit of the same or similar product
- Free repair of the defective product at the seller's expense
- Partial refund or discount on a future purchase as compensation
- Written apology or commitment by the business to correct its practices
- Escalation to adjudication if no settlement is reached
Mediation Timeline
Under DTI rules, the mediation conference must be scheduled within 15 working days from the filing of the complaint. The mediation itself typically lasts 1 to 3 sessions (each session lasting 1-2 hours). If a settlement is reached, the agreement is signed on the same day and becomes immediately binding. If no settlement is reached after a reasonable number of sessions, the mediator will declare a deadlock and the case will be forwarded for adjudication. The entire mediation process, from filing to resolution, typically takes 15 to 30 working days for straightforward cases.
Complete Example: Ana Files a Complaint About a Defective Appliance
Ana purchased a brand-new electric fan from a well-known appliance store in Manila for P3,500. After only two weeks of use, the fan stopped working entirely -- the motor burned out and began emitting a burning smell. When Ana brought the fan back to the store with her receipt and warranty card, the store refused to replace or repair it, claiming that the damage was due to "misuse." Ana knew she used the fan normally and decided to file a complaint with DTI. Here is her journey:
Gathered Evidence and Prepared Complaint
Ana organized her documents: the official receipt (P3,500), the warranty card (1-year warranty), photos of the defective fan showing the burned motor, and screenshots of her text messages with the store manager who refused the replacement. She wrote a complaint letter detailing the purchase date, the defect, and the store's refusal to honor the warranty. She requested a full refund or replacement unit.
Filed Complaint at DTI NCR Office
Ana visited the DTI National Capital Region (NCR) office at the DTI Main Office in Makati City. She filled out the complaint form, submitted her complaint letter and all supporting documents, and presented her valid ID. The DTI officer reviewed her documents, found them complete, and officially recorded her complaint. Ana received her complaint reference number: DTI-NCR-2025-00456. The filing was completely free.
DTI Sent Summons to the Appliance Store
DTI sent an official notice to the appliance store, informing them of Ana's complaint and summoning the store manager or authorized representative to a mediation conference. The notice included the date, time, and location of the mediation, as well as a copy of Ana's complaint. The store was given the opportunity to prepare a response.
Mediation Conference at DTI
Both Ana and the store manager attended the mediation conference at the DTI office. A DTI mediator facilitated the discussion. Ana presented her evidence -- the receipt, warranty card, and photos of the burned motor. The store manager initially maintained that the damage was due to misuse, but the mediator pointed out that a motor failure after only two weeks strongly suggests a manufacturing defect, not misuse, and that the warranty should be honored.
Settlement Reached
After the mediation discussion, the store agreed to provide Ana with a brand-new replacement fan of the same model and value, with a fresh 1-year warranty. Both parties signed the mediation agreement at the DTI office. The store was given 7 days to deliver the replacement unit to Ana.
Ana Received Her Replacement Fan
True to the mediation agreement, the store delivered a brand-new replacement fan to Ana within 5 days. Ana inspected the new unit, confirmed it was working properly, and signed the delivery receipt. She also received a new warranty card valid for 1 year. Ana then informed DTI that the case had been satisfactorily resolved.
Ana's Complaint Summary
Ana's only expense was transportation to the DTI office. The entire complaint process was free of charge.
Frequently Asked Questions
Can I file an anonymous complaint with DTI?
For formal complaints that will go through the mediation and adjudication process, you cannot file anonymously because the respondent business has the right to know who is filing against them, and both parties must attend the mediation conference. However, for tips or reports about price violations, overpricing, or safety concerns that require DTI monitoring or inspection (not individual case resolution), you may report anonymously through the 1-DTI (1-384) hotline or the DTI website. Anonymous tips are useful for triggering government inspections of erring businesses.
How long does the entire complaint process take?
The timeline varies depending on the complexity of the case and the cooperation of both parties. For straightforward cases that are resolved through mediation, the process typically takes 15 to 30 working days from the date of filing to the settlement. DTI is mandated to schedule the first mediation conference within 15 working days of filing. If mediation fails and the case proceeds to adjudication, the process can take an additional 30 to 90 days. Complex cases involving multiple parties or large amounts may take longer. In Ana's example above, the entire process from filing to resolution took only 20 calendar days.
Can businesses file consumer complaints too?
Yes, but with limitations. DTI's consumer complaint mechanism is primarily designed for individual consumers filing against businesses. However, a business may file a complaint against another business if it is acting as a consumer (i.e., it purchased a product or service from the other business for its own use, not for resale). For business-to-business disputes involving trade practices, unfair competition, or contract breaches, the appropriate forums may include the regular courts, the DTI Fair Trade Enforcement Bureau (FTEB), or arbitration bodies.
What happens if the business does not cooperate or attend the mediation?
If the respondent business fails to attend the mediation conference despite receiving proper notice, DTI may proceed with the case ex parte (without the respondent's participation). The complaint may be directly elevated to adjudication, where the DTI Adjudication Officer will decide the case based on the evidence presented by the complainant. Non-attendance by the respondent is noted and may work against them. DTI also has the authority to issue subpoenas to compel attendance. Repeated non-compliance can result in administrative penalties against the business, including fines and possible suspension or revocation of business permits.
Can I get a refund for a product I no longer want?
Philippine consumer law does not generally require businesses to accept returns or issue refunds for products that are not defective -- the "no return, no exchange" policy, while commonly posted in stores, is actually illegal under RA 7394 when applied to defective products. If the product is defective, substandard, or not as described, you have the right to demand a refund, replacement, or repair. However, if you simply changed your mind or no longer want the product (and it is not defective), the seller is generally not obligated to accept a return or issue a refund -- unless their store policy allows it. The key factor is whether the product has a defect or whether the seller made a misrepresentation.
What about online purchases? Can I file a DTI complaint for products bought online?
Yes, absolutely. DTI handles complaints involving online purchases, including products bought through e-commerce platforms (Shopee, Lazada, etc.), social media sellers (Facebook Marketplace, Instagram shops), and other online channels. Under the E-Commerce Act (RA 8792) and DTI Department Administrative Order No. 21-01, online sellers are subject to the same consumer protection rules as physical stores. When filing a complaint about an online purchase, make sure to include screenshots of the product listing, the order confirmation, payment proof, delivery receipts, and any communication with the seller. DTI can also coordinate with e-commerce platforms to help resolve disputes.
Is the "No Return, No Exchange" policy legal?
No. The "No Return, No Exchange" policy is illegal under Philippine law when applied to defective products. Under RA 7394 (Consumer Act), consumers have the right to return defective products and demand a refund, replacement, or repair -- regardless of any posted store policy. DTI has repeatedly warned businesses against displaying "No Return, No Exchange" signs and has fined establishments that refuse to honor consumer rights. If a store refuses to accept a return for a defective product citing this policy, you should file a complaint with DTI immediately.
Important Reminders
- Filing is completely free: DTI does not charge any fee for filing a consumer complaint. Do not pay any "processing fee" to fixers or intermediaries. If anyone asks you for money to file a DTI complaint, report them immediately.
- Keep your receipt and warranty card: Always keep your proof of purchase (official receipt or sales invoice) and warranty card in a safe place. These are the most important documents in any consumer complaint. If you purchase online, save screenshots and order confirmation emails.
- Try to resolve directly with the seller first: Before filing with DTI, it is advisable to first attempt to resolve the issue directly with the seller or business. Contact them in writing (text, email, or letter) and give them a reasonable time to respond. Document all communications -- this shows good faith and will strengthen your DTI complaint if direct resolution fails.
- Act promptly: File your complaint as soon as possible after discovering the issue. While there is no strict filing deadline for most consumer complaints, acting promptly preserves your evidence and demonstrates the seriousness of your claim. Warranty claims should be filed within the warranty period.
- "No Return, No Exchange" is illegal for defective products: Any business that refuses to honor a valid return for a defective product is violating RA 7394. Do not be intimidated by posted signs. You have the legal right to demand a refund, replacement, or repair for defective goods.
- Bring the defective product if possible: When attending the mediation conference, bring the actual defective product so that the mediator and the respondent can inspect it. This provides the strongest evidence of the defect.
- Attend the mediation conference: If you file a complaint, make sure to attend the scheduled mediation conference. Failure to attend may result in the dismissal of your complaint. If you cannot attend on the scheduled date, notify DTI in advance and request a rescheduling.
- Online purchases are covered: Products bought online (Shopee, Lazada, Facebook, Instagram, etc.) are covered by the same consumer protection laws as products bought in physical stores. Online sellers are subject to DTI jurisdiction and can be summoned to mediation just like any brick-and-mortar business.
