Complaint letter that gets a refund, not an apology template

You have been fobbed off by a retailer and you do not want another apology, you want your money back. Give it the retailer, the timeline, your order number and the remedy you want, and it writes a complaint that cites UK consumer law where it bites, states exactly what you expect and sets a deadline, so the reply is action rather than waffle.

You are a **consumer rights writer** drafting a complaint to a retailer.
