How to Make a Consumer Complaint

By Anita Rao, consumer-rights researcher · Updated 23 May 2026

Knowing how to make a consumer complaint effectively can save you time, money, and frustration when a product or service falls short. This guide walks through the practical steps to file a complaint, from first contact with the company to escalating with outside help if needed. Whether you need to complain about a company for a faulty product, poor service, or a billing dispute, having a clear process makes resolution far more likely. See also our guide to consumer rights.

Start by Contacting the Company Directly

The first step in how to make a consumer complaint is almost always to reach out to the business itself. Most companies would rather resolve an issue quietly than lose a customer or face a formal complaint, so give them the chance to make it right before escalating.

• Locate the company's official customer service contact (phone, email, or web form)
• Explain the problem clearly: what happened, when, and what outcome you want
• Stay factual and calm — a clear, polite complaint is taken more seriously
• Ask for a timeline on when you can expect a response

Put Your Complaint in Writing

If a phone call doesn't resolve things, follow up with a written consumer complaint by email or letter. Written communication creates a paper trail and often prompts a more considered response than a verbal exchange.

Include your name, contact details, order or account number, a summary of the issue, copies of relevant receipts or correspondence, and the specific resolution you're seeking (refund, repair, replacement, or apology). Keep the tone factual rather than emotional — it reads as more credible and is easier for the company to act on.

Keep Detailed Records Throughout

Good records are the backbone of any successful complaint about a company. Without them, it's much harder to prove your case if you need to escalate later.

• Save copies of receipts, contracts, invoices, and warranties
• Note the date, time, and name of anyone you speak with
• Keep all emails and screenshots of chat conversations
• Take photos of faulty products or damage where relevant
• Log every step you've taken and the responses you received

Escalate Within the Company

If frontline customer service doesn't resolve your issue, ask to escalate to a supervisor or the company's formal complaints department. Many larger companies have a dedicated complaints handling process, and some industries require businesses to offer one.

When escalating, reference your previous contact attempts, include the records you've kept, and restate clearly what resolution you're seeking. Set a reasonable deadline for a response before considering outside help.

Report to a Consumer Protection Agency

If the company fails to resolve your complaint, the next step is to file a complaint with a consumer protection agency or relevant regulator in your country or region. These organizations can't always force a resolution, but a documented pattern of complaints can prompt investigation and pressure companies to act.

Look for a national or local consumer protection authority, an industry-specific ombudsman or regulator, or a recognized consumer rights organization. Provide them with the same records you compiled earlier, since a clear timeline and evidence trail make your case stronger.

Consider Additional Options if Needed

For disputes that remain unresolved, additional avenues may be available depending on your situation and location, such as mediation services, small claims court, or a chargeback request through your bank or card provider if you paid by card.
