Consumer Complaint Letter to PROFECO Mexico (Queja ante la PROFECO)

A Consumer Complaint Letter to PROFECO Mexico (Queja ante la PROFECO) is a formal written document submitted by a consumer (consumidor) to the Procuraduría Federal del Consumidor (PROFECO) — Mexico's federal consumer protection authority — to initiate a complaint against a supplier (proveedor) for violations of the Ley Federal de Protección al Consumidor (LFPC, published in the DOF on 24 February 1992, as frequently amended). PROFECO processes consumer complaints under LFPC Articles 24 and 25, which establish the agency's powers to receive complaints, conduct conciliation between consumers and suppliers, and impose administrative sanctions for LFPC violations.

LFPC Article 24 enumerates PROFECO's broad institutional powers — including receiving and processing consumer complaints (quejas), conducting conciliation proceedings (conciliaciones) between consumers and suppliers, conducting inspections (visitas de verificación) to commercial establishments, imposing administrative fines (multas) and sanctions on suppliers who violate the LFPC, and maintaining the Registro Público de Consumidores (public consumer registry). LFPC Article 25 empowers PROFECO to act ex officio when it detects systematic consumer protection violations, and to apply the LFPC's sanctions regime — fines, temporary closure orders (clausura temporal), and in serious cases referral to the Fiscalía General de la República (FGR) for criminal investigation.

Mexican consumer protection law creates an asymmetric protective framework — the LFPC establishes consumer rights and supplier obligations that favor consumers in disputes, reflecting the structural inequality of bargaining power between individual consumers and organized commercial suppliers. Key consumer rights protected by the LFPC include: the right to accurate information about products and services (LFPC Article 7); the right to non-discriminatory treatment by suppliers (LFPC Article 8); the right to real and verifiable pricing (LFPC Article 7-bis); the right to product warranty (garantía) of at least 90 days for durable goods under LFPC Article 77; the right to contract rescission or replacement for defective goods under LFPC Article 92; and the right to effective redress through PROFECO procedures.

PROFECO handles complaints involving all types of commercial suppliers — retail stores (tiendas departamentales like Liverpool, Palacio de Hierro, Coppel), telecommunications providers (Telcel, Telmex, AT&T México — regulated jointly by PROFECO and IFT), automotive dealers, travel agencies, construction companies, financial service providers (jointly regulated with CONDUSEF), and e-commerce platforms. PROFECO's Concilianet online platform and its network of delegaciones regionales in all 32 states process hundreds of thousands of quejas annually — PROFECO's annual reports consistently show automotive, telecommunications, and retail as the highest-complaint sectors.

The LFPC's conciliation mechanism (LFPC Articles 111–117) is the primary dispute resolution pathway — a PROFECO conciliador facilitates a structured meeting between the consumer and supplier to reach a mutually acceptable resolution without litigation. Conciliation is mandatory before PROFECO can initiate administrative sanction proceedings against a supplier in most cases. If conciliation fails, PROFECO may proceed to investigate and sanction the supplier, and the consumer may pursue civil litigation before the civil courts or arbitration through PROFECO's arbitration procedure under LFPC Articles 118–131.

PROFECO's digital transformation under the Estrategia Digital Nacional has significantly expanded consumers' ability to file and track complaints online. The Concilianet platform processes over 80% of all PROFECO complaints electronically and enables real-time tracking of complaint status, scheduling of conciliation hearings via video conference, and electronic signing of convenios conciliatorios — reducing the need for consumers to appear in person at PROFECO offices. The platform integrates with the SAT's RFC verification system to confirm supplier identity and with the Buro de Entidades Financieras database for financial sector complaints.

A Consumer Complaint Letter to PROFECO Mexico is needed whenever a consumer has suffered a violation of their rights under the Ley Federal de Protección al Consumidor by a supplier and wishes to initiate PROFECO's formal conciliation and complaint process.

The letter is required when a consumer purchased a defective product and the supplier refuses to honor the legal warranty — LFPC Article 77 establishes a minimum 90-day warranty for durable goods, and LFPC Article 92 entitles the consumer to choose between product repair, replacement, or a full refund when the product has a manufacturing defect that cannot be repaired within 30 days.

The complaint letter is needed when a telecommunications provider (Telcel, Telmex, Izzi, Megacable, AT&T) charges amounts not agreed in the contract, fails to provide the contracted service quality, imposes unjustified service interruptions, or refuses to honour promotional prices — PROFECO handles telecom consumer complaints jointly with the IFT (Instituto Federal de Telecomunicaciones) under the Ley Federal de Telecomunicaciones y Radiodifusión.

The letter is required when an automotive dealer refuses to apply recall repairs (reparaciones de campaña) free of charge, charges for warranty repairs covered under the manufacturer's warranty, or misrepresents vehicle specifications at the point of sale — the automotive sector consistently generates the highest volumes of PROFECO complaints in Mexico.

A PROFECO complaint is needed when a construction company or home developer (desarrollador inmobiliario) fails to deliver a property on time, delivers a property with construction defects (vicios ocultos or defectos aparentes), or imposes unilateral contract modifications — PROFECO's jurisdiction extends to residential real estate purchase agreements under the LFPC.

The complaint letter is also required when a travel agency, airline, or hotel fails to honor contracted services, imposes hidden charges (cargos ocultos), or refuses to process refunds after service cancellation — PROFECO actively enforces consumer rights in the tourism sector.

Under LFPC Articles 24–25 and 97, the formal written queja submitted to PROFECO is the foundational document that initiates the conciliation procedure — without it, PROFECO cannot formally call the supplier to a conciliation meeting or investigate the complaint.

The complaint letter is also required when a consumer has been subject to discriminatory service practices (practicas discriminatorias) by a supplier — LFPC Article 8 prohibits suppliers from refusing service, applying different prices, or offering inferior quality based on the consumer's gender, nationality, ethnicity, or other protected characteristics. PROFECO has jurisdiction over discriminatory commercial practices and may impose enhanced sanctions under LFPC Article 128 for violations involving discrimination, complementing the protections available under the Ley Federal para Prevenir y Eliminar la Discriminacion (LFPED).

A valid Consumer Complaint Letter to PROFECO Mexico under Ley Federal de Protección al Consumidor Articles 24–25 must contain the following essential elements to enable PROFECO to process the complaint and summon the supplier to conciliation:

Consumer Identification: Full legal name of the consumer filing the complaint; CURP; RFC (if applicable); current domicile and postal code; primary telephone number; and email address. PROFECO's Concilianet platform requires this information for account registration and case tracking. Consumers should provide accurate contact information as PROFECO uses it to schedule and confirm conciliation appointments.

Supplier Identification: Full legal name (razón social) of the supplier being complained against; RFC; the specific branch or establishment address where the transaction occurred; telephone and email of the supplier if known; and the name of any specific employee or manager who interacted with the consumer. Accurate supplier identification is critical — PROFECO uses the RFC to formally summon the supplier to the conciliation hearing.

Transaction Description: A clear, chronological description of the transaction — date and location of purchase or service agreement; description of the product or service acquired; price paid and payment method; any contract, invoice, ticket, or receipt number; and the advertised or contracted specifications of the product or service. The transaction documentation (receipts, contracts, warranties) should be attached as evidence.

Description of the Problem: A specific and factual description of how the supplier violated the consumer's rights under the LFPC — for example, the product stopped working within the warranty period; the supplier refused to honour the published price; the service delivered did not match the contracted specifications; hidden charges appeared on the invoice; or the supplier refused to process a lawful refund. The problem description should distinguish facts from conclusions and avoid emotional language.

Prior Complaint Attempts: Documentation of attempts to resolve the matter directly with the supplier before approaching PROFECO — dates of telephone calls, emails, or in-person visits to the supplier's customer service, and the supplier's responses (or non-responses). PROFECO conciliators give weight to evidence that the consumer attempted direct resolution in good faith before filing the queja.

Remedy Requested: A specific statement of what the consumer is seeking from the conciliation — full refund of purchase price; replacement of defective product; execution of warranty repair at no cost; delivery of contracted service; cancellation of unauthorized charges; or compensation for damages caused by the defective product or service. The remedy requested must be proportionate and legally justified under the LFPC.

Evidence List: A list of all supporting documents attached to the complaint — purchase receipts (comprobantes de compra), contracts, warranty certificates (pólizas de garantía), product photos, email or WhatsApp correspondence with the supplier, payment bank statements, and any photographs of defective products or unsatisfactory services.

Signature and Date: The consumer's handwritten signature or electronic signature (for Concilianet online submissions), with the date and place of filing. PROFECO accepts complaints filed online through Concilianet, in person at any PROFECO delegación, or by telephone through Tel-PROFECO at 800-468-8722.
