A complaint letter works when it keeps what happened separate from how you feel about it. A clear timeline, any reference numbers, and one specific request give the reader something to act on.

A text to start with
Help me write a complaint letter to [company or department] about [the problem, e.g. a delayed order, a billing error, a service failure]. Here's the timeline: [list what happened and when]. My reference numbers are [order number, ticket number, etc., or 'none']. I want [specific remedy, e.g. a refund, a replacement, a written explanation]. Keep the tone firm but not angry.
Example request. Change the details to fit your situation.
What to check in the draft
Dates and reference numbers must match what you provided, since a wrong number can delay the response. The draft shouldn't claim legal violations or assert anything you can't document. One request is easier to act on than three, so if the draft lists several, decide which matters most. Cut emotional language you didn't supply.
After you review the draft
Attach or reference any documents you mentioned, such as receipts, screenshots, or earlier correspondence. Keep a copy of the letter and the date you sent it. Check the company's website for a complaints process or escalation contact, and send the letter there instead of a general inbox. Confirm any refund or return terms with the company itself.
