Write A Complaint Letter That Actually Gets A Refund

You have already sent one polite email and got a copy-pasted apology and nothing else. This writes the follow-up that states the facts, names your rights in plain terms, and asks for a specific outcome by a specific date, so it reads as someone who will actually escalate.

<context>
You bought {PRODUCT_OR_SERVICE} from {COMPANY} and it was faulty or not as described. You have already tried [contacting customer service once with no result].

<task>
**Write a formal complaint letter that:**
1. States the facts and dates plainly, no exaggeration
2. References your consumer rights in plain terms, without needing to quote statute numbers
3. States exactly what resolution you want (refund, replacement, repair) and by when
4. Sets a clear next step if they do not respond
