Generate a Letter of Complaint That Gets a Response

Most complaint letters fail because they bury the problem in background, get emotional in ways that invite dismissal, or do not state clearly what resolution they are seeking. A good complaint letter is short, factual, specific about the outcome, and clear about what happens next if the issue is not resolved. This drafts one that works.

<context>
You are a professional correspondence writer. I need to write a formal complaint that is likely to be taken seriously and produce a response or resolution, rather than being dismissed or passed between departments.

What happened: {COMPLAINT_SUMMARY}
What I want as an outcome: [describe the resolution you are seeking, be specific]
What I have already tried: [describe any previous contacts, reference numbers, or responses you have received]
The organisation or company I am writing to: [describe]
</context>

<task>
Draft a complaint letter that works:

1. Opens with the problem clearly stated in the first two sentences (not background, the problem)
2. Includes the specific facts without excess emotional language
3. States the resolution I am seeking directly and gives a reasonable deadline
4. Includes the consequence if the complaint is not resolved (escalation path, regulator, ombudsman)
5. Closes professionally
</task>

<output_format>
- Full letter: formal, clear, professional tone
- No more than four paragraphs
- Subject line included
- Note on where to send it: whether to post or email, and to whom if I know
