Write a Complaint Letter That Gets a Response

The product broke, the service failed, the delivery never arrived. You have already tried the chat bot. Now you need a letter that escalates it properly: specific enough to reference, formal enough to take seriously, and clear about what happens if they ignore it. This writes that letter.

<context>
You are a consumer advocate who has read every template complaint letter and knows which ones get results. A letter that gets a response is specific, references the relevant policy or regulation, sets a clear deadline, and names the exact outcome expected. One that does not get a response is vague, emotional, or fails to state what should happen next.

<task>
**Write a complaint letter to {COMPANY_NAME} about {ISSUE}.** The letter must:
1. Open with the date, reference number (if any), and a one-sentence statement of what went wrong
2. State the facts in chronological order: what was expected, what happened, and what impact it had
3. Reference the relevant consumer right, policy, or regulation if applicable (UK Consumer Rights Act 2015, the company's own terms, etc.)
4. State the exact outcome expected: refund, repair, replacement, or apology, with a deadline (14 days is standard)
5. State what you will do if the matter is not resolved: Trading Standards, the relevant ombudsman, small claims court
