How to File a Complaint Against a Supplier for Breach of Contract and Refund Issues

A supplier who takes payment but fails to deliver, delivers defective goods, refuses a valid refund, or ignores warranty obligations can be held liable in the Philippines. The correct remedy depends on what kind of transaction you had: an ordinary contract, a consumer purchase, an online transaction, or a business-to-business supply deal. This guide explains how to prepare your evidence, where to file, what legal basis to use, and when a DTI complaint, barangay conciliation, small claims case, or civil action is the better route.

What Counts as Breach of Contract by a Supplier?

A breach of contract happens when one party fails to do what they promised under the agreement. With suppliers, common examples include:

  • You paid a deposit or full price, but the goods were never delivered.
  • The supplier delivered the wrong item, wrong quantity, or substandard materials.
  • A contractor or service provider failed to complete the work.
  • The product had defects and the supplier refused repair, replacement, or refund.
  • The supplier promised a refund but kept delaying or stopped replying.
  • The supplier changed the agreed price, specifications, or delivery date without your consent.

A contract does not always have to be a formal notarized document. Under Article 1356 of the Civil Code, contracts are generally binding “in whatever form” as long as the essential requisites are present, although certain contracts must be in writing to be enforceable. Messages, invoices, purchase orders, quotations, official receipts, bank transfer slips, delivery receipts, and email confirmations can help prove the agreement. (Lawphil)

Under Article 1159 of the Civil Code, obligations arising from contracts have the force of law between the parties and must be complied with in good faith. If the supplier is guilty of fraud, negligence, delay, or otherwise violates the terms of the obligation, Article 1170 makes the supplier liable for damages. (Lawphil)

Your Main Legal Remedies Under Philippine Law

1. Demand performance, refund, rescission, or damages

For ordinary contracts, the Civil Code gives the injured party practical choices. Article 1191 provides that in reciprocal obligations, such as “I pay, you deliver,” the injured party may choose between:

  • Fulfillment — asking the supplier to deliver, repair, complete, or perform what was promised; or
  • Rescission — cancelling or undoing the contract, usually with return of what was paid;

In either case, the injured party may also claim damages when legally supported. (Lawphil)

For sale of goods, Article 1599 of the Civil Code specifically allows a buyer, in case of breach of warranty, to keep the goods and claim damages, refuse the goods, or rescind the sale and recover the price paid after returning or offering to return the goods. (Lawphil)

2. Use consumer protection remedies if you are a consumer

If you bought goods or services for personal, family, household, or similar use, your case may fall under Republic Act No. 7394, or the Consumer Act of the Philippines. The Consumer Act protects buyers from deceptive, unfair, and unconscionable sales practices, including false claims about quality, grade, performance, warranty, or availability. (Supreme Court E-Library)

For defective or imperfect products, Article 100 of the Consumer Act makes suppliers jointly liable for imperfections that make products unfit or inadequate for their intended use, decrease their value, or make them inconsistent with labels, packaging, advertisements, or other product information. If the defect is not corrected within 30 days, the consumer may demand replacement, immediate reimbursement, or a proportionate price reduction. (Supreme Court E-Library)

For defective services, Article 102 allows the consumer to demand performance of the service without additional cost, immediate reimbursement, or a proportionate price reduction. (Supreme Court E-Library)

The Supreme Court applied these principles in Mazda Quezon Avenue v. Caruncho, where it held that a supplier may be liable for product imperfections it cannot resolve within the warranty period. The Court recognized the consumer’s right to reimbursement when the defect persisted despite repeated repairs. (Supreme Court E-Library)

3. Know when “No Return, No Exchange” does not apply

A “No Return, No Exchange” policy cannot defeat your rights when the item is defective. DTI materials explain that there is no such thing as “No Return, No Exchange” for defective products, although a mere change of mind does not automatically entitle the buyer to refund or exchange.

In simple terms:

Situation Usually refund-worthy? Why
Defective item discovered after purchase Yes, depending on facts Consumer Act and warranty rules may apply
Item does not match sample, ad, box, or agreed specs Yes, depending on proof Misrepresentation or breach of warranty
Service was not properly rendered Yes, repair/reperformance/refund may apply Article 102 of the Consumer Act
Buyer simply changed their mind Usually no DTI says change of mind alone is not enough
Buyer damaged the item through misuse Usually no Supplier may raise buyer fault as a defense

DTI Complaint, Small Claims, or Civil Case: Which One Should You File?

Choosing the wrong forum wastes time. Use this as a practical guide.

Your situation Usually appropriate forum Best for
Consumer purchase, defective product, warranty refusal, misleading sales act DTI consumer complaint Mediation, refund, replacement, administrative action
Online purchase from merchant/platform Platform redress first, then DTI/ODR or DTI complaint Online refund, non-delivery, defective item
Pure money claim up to ₱1,000,000 Small claims court Fast collection or refund claim
Business-to-business supply contract Small claims or ordinary civil action, depending on amount and issues Commercial refund, unpaid delivery, breach
Claim above ₱1,000,000 or with complex damages/injunction Summary or ordinary civil action Larger or more complicated disputes
Fraud existed from the start, not just non-payment/non-delivery Prosecutor’s office may be relevant Possible estafa, if evidence supports deceit

DTI handles consumer complaints under the Consumer Act and other fair trade laws. Its Fair Trade Enforcement Bureau states that consumer complaints may involve product quality and safety, deceptive or unfair sales practices, “No Return, No Exchange” violations, warranties, labeling, liability for products and services, misleading advertisements, and repair/service firms. (Fair Trade Enforcement Bureau)

Small claims, on the other hand, are for money claims. The Supreme Court’s Rules on Expedited Procedures increased the small claims threshold to ₱1,000,000, covering money owed under contracts involving services and sale of personal property. Small claims cases generally have one hearing day, with judgment rendered within 24 hours after termination, and the decision is final, executory, and unappealable. (Supreme Court of the Philippines)

Special Rules for Online Supplier and Refund Issues

Online transactions are now covered by Republic Act No. 11967, or the Internet Transactions Act of 2023. It applies to business-to-business and business-to-consumer internet transactions within DTI’s mandate where one party is in the Philippines, or where the online merchant, e-retailer, or platform targets the Philippine market and has minimum contacts here. (Supreme Court E-Library)

For online refund disputes, three rules are especially important:

  1. Use the platform or seller’s internal redress first. Under Section 24 of RA 11967, an aggrieved party must use the internal redress mechanism of the digital platform, e-marketplace, or e-retailer before filing with a court, government agency, or ADR body. This is considered exhausted if unresolved after seven calendar days. (Supreme Court E-Library)

  2. Online consumers may pursue repair, replacement, refund, or other remedies. Section 20 gives online consumers remedies in case of defect, malfunction, loss without the consumer’s fault, failure to conform with warranty, or other liability arising from the contract. If replacement or refund is chosen, the online merchant is generally entitled to the return of the original goods without cost to the online consumer, unless otherwise agreed. (Supreme Court E-Library)

  3. The online merchant is primarily liable. Section 25 makes the e-retailer or online merchant primarily liable to indemnify the online consumer in civil actions or administrative complaints arising from the internet transaction. E-marketplaces or digital platforms may become subsidiarily or solidarily liable in specific cases, such as failure to exercise ordinary diligence or failure to remove unsafe or prohibited goods after notice. (Supreme Court E-Library)

Step-by-Step Guide: How to File a Complaint Against a Supplier

1. Identify exactly what the supplier promised

Before filing anything, write down the agreement in plain language:

  • What did you order?
  • How much did you pay?
  • When was delivery or completion due?
  • What specifications, brand, model, quantity, or quality were promised?
  • Was there a warranty?
  • What exactly went wrong?
  • What remedy do you want: delivery, repair, replacement, refund, price reduction, damages, or cancellation?

This matters because agencies and courts decide based on proof, not frustration alone.

2. Organize your evidence

Prepare a clean evidence folder. For mobile screenshots, capture the full conversation showing names, dates, numbers, and payment instructions.

Common evidence includes:

  • Contract, quotation, purchase order, invoice, acknowledgment receipt, official receipt, or sales invoice
  • Bank transfer slip, GCash/Maya receipt, credit card statement, remittance proof, or deposit slip
  • Delivery receipt, waybill, tracking record, or proof of non-delivery
  • Product photos and videos showing defects
  • Warranty card, manual, packaging, advertisement, listing, or product description
  • Chat logs, emails, text messages, and call logs
  • Repair reports, inspection reports, or technician findings
  • Demand letter and proof the supplier received it
  • Valid government ID or passport
  • Business name, SEC registration, DTI business name, address, contact number, and platform profile of the supplier

For foreigners or Filipinos abroad, a representative in the Philippines may need a Special Power of Attorney (SPA). If signed abroad, the SPA is commonly notarized in the foreign country and authenticated by apostille if the country is a party to the Apostille Convention, or consularized if apostille is not available. Courts, banks, and agencies may be strict about this because the representative will sign, appear, or receive documents on your behalf.

3. Send a written demand before filing

A demand letter is not always required for every case, but it is very useful. Article 1169 of the Civil Code provides that delay generally begins when the creditor judicially or extrajudicially demands fulfillment, unless demand is unnecessary under the law or circumstances. A written demand may also interrupt prescription under Article 1155. (Lawphil)

A practical demand letter should include:

  • Your name and contact details
  • Supplier’s name, business name, and address
  • Date of transaction
  • Amount paid
  • Summary of the breach
  • Your requested remedy
  • A reasonable deadline, usually 5 to 15 calendar days depending on urgency
  • A statement that you will file with DTI, barangay, or court if unresolved
  • Attachments: proof of payment, invoice, screenshots, photos

Keep proof of sending: email sent copy, courier receipt, registered mail receipt, screenshot of message delivery, or notarized demand if the amount is large.

4. For online purchases, exhaust the platform or seller redress mechanism

If your transaction happened through an e-commerce platform, marketplace, social media shop, delivery app, online travel platform, or website, file first through the platform’s refund/return/dispute channel. Save the ticket number and screenshots.

If the dispute remains unresolved after seven calendar days, Section 24 of RA 11967 treats the internal redress mechanism as exhausted. (Supreme Court E-Library)

5. File a DTI consumer complaint if it is a consumer transaction

For consumer complaints, DTI accepts complaints through its Consumer Complaints Assistance and Resolution (CARe) System, by email, or in person depending on location. The DTI-FTEB FAQ states that complainants in Metro Manila may submit complaints through the online portal, by sending the accomplished complaint form or complaint letter by email, or by filing in person at the Fair Trade Enforcement Bureau in Makati. (Fair Trade Enforcement Bureau)

DTI’s consumer complaint guide says the complaint form or letter should include:

  1. Complete name, address, email, and contact number of the complainant and respondent
  2. Narration of facts
  3. Demand
  4. Scanned proof of transaction and government-issued ID (esigaw.dti.gov.ph)

DTI Department Administrative Order No. 20-02, Series of 2020 also contains a “No-Wrong-Door” policy, meaning a consumer complaint filed with DTI may be accepted for appropriate assistance even if the subject matter does not fall under DTI jurisdiction, subject to legal limitations.

6. Attend DTI mediation

DTI mediation is meant to help both sides settle without a full-blown case. DTI’s Mediation Division conducts mediation under Article 159 of the Consumer Act and DAO 20-02. (Fair Trade Enforcement Bureau)

Possible outcomes include:

  • Supplier agrees to refund
  • Supplier agrees to repair or replace
  • Supplier offers partial refund or store credit
  • Parties sign a settlement agreement
  • Mediation fails and DTI issues a Certificate to File Action

Be specific during mediation. Instead of saying “I want justice,” say:

  • “I want a full refund of ₱45,000 because the item was never delivered.”
  • “I want replacement with the correct model within 7 days.”
  • “I want refund less reasonable use, if DTI finds deduction proper.”
  • “I want reimbursement of delivery and inspection costs.”

7. If mediation fails, proceed to DTI adjudication

DTI states that a formal consumer complaint may be filed with the Adjudication Division after mediation, upon issuance of a Certificate to File Action. Mediation is mandatory and a condition precedent to filing a formal consumer complaint. DTI also states that there is no filing fee for adjudication if the complaint is sufficient in form and the requirements are complete. (Fair Trade Enforcement Bureau)

For DTI adjudication, the required documents include a verified, dated, and signed complaint form containing the parties’ names and addresses, concise facts, sworn statements or documentary evidence, reliefs prayed for, Certificate of Non-Forum Shopping, and the Certificate to File Action. (Fair Trade Enforcement Bureau)

DTI adjudication is more formal than mediation. Expect position papers, documentary evidence, and possible clarificatory proceedings. Article 164 of the Consumer Act allows administrative sanctions such as cease and desist orders, voluntary assurance of compliance, recall, replacement, repair, refund, reimbursement, restitution, rescission, and administrative fines. (Supreme Court E-Library)

8. Check if barangay conciliation is required before court

If you plan to go to court, ask whether Katarungang Pambarangay applies. Supreme Court Circular No. 14-93 states that prior barangay conciliation is generally a pre-condition before filing a complaint in court or government offices, subject to exceptions under the Local Government Code. (Lawphil)

In practice, barangay conciliation is usually relevant when:

  • Both parties are natural persons;
  • They actually reside in the same city or municipality, or in adjoining barangays in different cities/municipalities where the law allows; and
  • The case is not covered by an exception.

It is often not required when the respondent is a corporation, when parties live in different cities not covered by the barangay rules, when urgent court action is needed, or when the law provides another exception. If required, get a Certificate to File Action from the barangay before filing in court.

9. File a small claims case if your goal is to recover money up to ₱1,000,000

If DTI is not the right forum, or if you simply want to recover money, small claims may be the fastest court remedy.

Small claims may fit if:

  • You want a refund or reimbursement;
  • Your claim is ₱1,000,000 or below, excluding interest and costs;
  • The claim arises from sale of personal property, services, loans, lease, or similar contracts;
  • You are not asking for complicated injunctions or recovery of property.

The Supreme Court’s small claims page provides downloadable forms, including Statement of Claim, Response, Special Power of Attorney, Motion for Execution, and other templates. (Office of the Court Administrator)

Typical filing steps:

  1. Go to the proper first-level court: Metropolitan Trial Court, Municipal Trial Court in Cities, Municipal Trial Court, or Municipal Circuit Trial Court.
  2. Ask for the Small Claims forms or download them from the Office of the Court Administrator page.
  3. Fill out the Statement of Claim.
  4. Attach all evidence.
  5. Attach barangay Certificate to File Action if required.
  6. Pay filing and service fees assessed by the Clerk of Court, unless allowed to litigate as an indigent.
  7. Attend the hearing personally or through a properly authorized representative.
  8. Bring originals and copies of documents.

Small claims hearings are designed to be simpler and faster. The Supreme Court has stated that the Rules allow only one hearing day, with judgment rendered within 24 hours after termination, and the decision is final, executory, and unappealable. (Supreme Court of the Philippines)

10. File an ordinary civil case for larger or more complex claims

A regular civil action may be necessary if:

  • The claim exceeds the small claims threshold;
  • You need injunction, specific performance, or other relief beyond simple money recovery;
  • The contract involves complex construction, commercial, or technical issues;
  • Multiple parties are involved;
  • The supplier has counterclaims or complicated defenses;
  • You are claiming substantial damages that need formal proof.

Civil Code prescription periods matter. Actions upon a written contract generally prescribe in 10 years, while actions upon an oral contract generally prescribe in 6 years. Special laws may provide shorter periods, such as the Consumer Act’s two-year prescription rule for Consumer Act claims. (Lawphil)

Required Documents, Fees, and Timelines

Process Key documents Filing fee Practical timeline
Supplier demand Demand letter, proof of payment, contract, screenshots Usually none, except notarization/courier 5–15 days for response
Platform dispute Order ID, photos, chat logs, delivery proof, refund ticket Usually none Internal redress deemed exhausted after 7 calendar days if unresolved under RA 11967
DTI initial complaint Complaint form or letter, proof of transaction, ID, evidence Usually none for complaint filing Intake and mediation schedule vary by office and caseload
DTI adjudication Verified complaint, Certificate to File Action, sworn statements, evidence, Certificate of Non-Forum Shopping DTI states no filing fee if requirements are complete Often several weeks to months, depending on complexity and submissions
Barangay conciliation Complaint, IDs, proof of residence, evidence Minimal barangay fees, if any Often a few weeks, depending on hearing dates
Small claims Statement of Claim, evidence, barangay CFA if required, SPA if representative Assessed by court based on amount and service needs Designed for fast resolution; one hearing day and judgment within 24 hours after termination
Ordinary civil action Complaint, verification, certification, evidence, filing fees Based on amount and reliefs claimed Months to years depending on court, service, evidence, and appeals

Common Pitfalls That Weaken Refund and Breach Complaints

Filing with DTI when it is really a business-to-business collection case

DTI is usually strongest for consumer complaints. If you are a business buyer suing another business supplier for a commercial supply contract, a small claims or civil action may be more direct. RA 11967 covers certain online B2B transactions, but money recovery may still require court action depending on the issue.

Relying only on screenshots without proving payment

Screenshots of promises help, but proof of payment is often the heart of a refund claim. Keep receipts, bank records, remittance slips, and payment confirmations.

Returning the item without documenting its condition

Before returning a defective item, take photos and videos from multiple angles. Record serial numbers, packaging, accessories, and the defect. For expensive items, an independent inspection report can be valuable.

Waiting too long

Delay can hurt both legally and practically. Evidence disappears, chats get deleted, sellers change accounts, and prescription periods may run. Consumer Act claims generally prescribe within two years from the transaction, deceptive or unfair act, or discovery of hidden defects, subject to how courts apply warranty-related facts. In Mazda Quezon Avenue v. Caruncho, the Supreme Court recognized that the two-year period may be reckoned from the end of the warranty period where the supplier continuously attempted to repair the defect during warranty. (Supreme Court E-Library)

Treating every refund refusal as estafa

A breach of contract is usually civil. Estafa under Article 315 of the Revised Penal Code requires fraud or deceit, and for false pretenses, the fraudulent act must generally exist before or at the same time the victim parts with money. A supplier’s later failure to deliver is not automatically estafa if the original transaction was genuine but later went bad. (Lawphil)

Frequently Asked Questions

Can I file a complaint if the supplier did not deliver after I paid?

Yes. If it was a consumer transaction, you may file with DTI, especially if there was deception, non-delivery, or refusal to refund. If your goal is simply to recover money and the amount is ₱1,000,000 or less, small claims may also be appropriate.

Is DTI better than small claims court?

DTI is often better for consumer complaints involving defective products, warranty issues, misleading sales practices, and supplier violations of consumer laws. Small claims is often better when you want a money judgment for a clear refund or unpaid obligation. Some people start with DTI mediation because it is simpler and may lead to settlement, then go to court if the dispute remains unresolved.

Can I get a refund if the item is defective but the store says “No Return, No Exchange”?

Yes, if the defect is legally proven and not caused by your misuse. DTI materials state that “No Return, No Exchange” does not apply to defective products, although a change of mind alone does not entitle the buyer to refund or exchange.

Do I need an official receipt to file a complaint?

An official receipt or sales invoice is very helpful, but it is not the only possible proof. Bank transfers, chat confirmations, delivery receipts, platform order records, emails, and written acknowledgments may also help prove the transaction. However, lack of proof of purchase is a common weakness, so gather as much supporting evidence as possible.

Can a foreigner file a complaint against a Philippine supplier?

Yes, a foreigner can file a complaint or civil case in the Philippines if the transaction and forum requirements are met. If the foreigner is abroad, a representative may need a properly executed SPA, usually apostilled or consularized depending on the country of signing.

What if the online seller is abroad but sold to buyers in the Philippines?

RA 11967 has extraterritorial application when a person engaging in e-commerce avails of the Philippine market and has minimum contacts in the Philippines. In practice, enforcement is easier when there is a Philippine platform, payment channel, local representative, registered business, or identifiable contact information. (Supreme Court E-Library)

How long does a DTI complaint take?

Mediation may be scheduled depending on the DTI office’s caseload and the parties’ availability. If mediation fails and the case moves to adjudication, expect a more formal process with submissions and evidence. DTI rules aim for efficient resolution, but actual timelines vary based on completeness of documents, service of notices, attendance, and complexity.

Can I claim attorney’s fees, transportation, shipping, and other expenses?

You may claim them if they are legally and factually supported, but not every expense is automatically awarded. Article 2208 of the Civil Code limits recovery of attorney’s fees and litigation expenses to specific situations, such as when the defendant’s act compelled the plaintiff to incur expenses to protect their interest, when the defendant acted in gross and evident bad faith, or when the court finds it just and equitable. (Lawphil)

What if the supplier offers repair but I want a refund?

It depends on the law, warranty, and facts. Under the Consumer Act, certain product imperfections may first be corrected, but if not corrected within the applicable period, the consumer may demand replacement, reimbursement, or price reduction. For express warranty breach, the Consumer Act also recognizes repair or refund remedies, subject to rules on reasonable use and the circumstances of the defect. (Supreme Court E-Library)

Can I file both DTI and a court case?

Be careful. Multiple filings over the same transaction may create procedural problems, especially if you are asking for the same relief. DTI adjudication requires a Certificate of Non-Forum Shopping for formal complaints, meaning you must disclose whether you have filed or are filing related cases. (Fair Trade Enforcement Bureau)

Key Takeaways

  • A supplier’s failure to deliver, defective delivery, warranty refusal, or refund delay may be a breach of contract, consumer law violation, or both.
  • For ordinary contracts, Civil Code Articles 1170 and 1191 support claims for damages, fulfillment, rescission, and refund.
  • For consumer purchases, RA 7394 gives remedies such as repair, replacement, reimbursement, price reduction, and DTI complaint procedures.
  • For online transactions, RA 11967 requires internal platform or seller redress first; if unresolved after seven calendar days, the remedy is considered exhausted.
  • DTI is usually best for consumer protection issues; small claims is often best for clear money claims of ₱1,000,000 or below.
  • Barangay conciliation may be required before court in certain disputes involving individuals residing in the same city or municipality.
  • Evidence matters: contracts, receipts, screenshots, proof of payment, delivery records, defect photos, warranty documents, and demand letters can make or break the case.
  • A refund refusal is not automatically estafa; criminal fraud requires proof of deceit, usually existing before or at the time payment was made.
