Sample Customer Complaint Letter

Share this page

Effective complaint letters explain the problem and how you’d like the company to resolve it. Try to be clear and include only the details you need to describe the problem and the resolution you want.

Information To Include in Your Letter

Avoid writing an angry, sarcastic, or threatening letter. The person reading it probably didn’t cause the problem, but may be very helpful in resolving it.

Give the basics

  • Include your name, address, and phone number.
  • Include your account number, if you have an account with the company.
  • Give the product name and its serial or model number.
  • State the date and place of purchase.

Tell your story

  • Explain the problem.
  • Give a brief history of your efforts to resolve the problem, if the information helps explain why you’re writing to the company.

Tell the company how you want to resolve the problem

  • State the solution you want, like a refund, repair, exchange, or store credit. Or, consider asking the company to suggest a resolution.
  • List the documents you’re enclosing, if any. Remember — only send copies, not originals.
  • Let them know how to reach you.

Be reasonable

File your complaint

  • Send your letter by certified mail, return receipt requested. Keep a copy for yourself.
  • If you file your complaint online, print the screen or take a screenshot before you hit “submit.”

Report Fraud or Deception

If you think a company or seller has been dishonest, contact your state attorney general or consumer protection office. Tell the Federal Trade Commission too, at ReportFraud.ftc.gov. The FTC doesn’t resolve individual complaints, but your report helps law enforcement detect patterns of wrongdoing and may lead to an investigation.
