Strongly Worded
AI complaint letter writer to get a refund
The €249 headphones arrived with a dead left earcup. Three weeks and three support chats later, you've been told "we've escalated your case" twice and you still don't have a refund. Your draft is either furious or so polite they'll ignore it.

Sample you can paste
Company: SoundHaus online shop, customer service by email. What I bought: Aria Pro noise-cancelling headphones, EUR 249, order #48213, ordered 29 September 2026, delivered 1 October. What went wrong: left earcup gives no sound at all, from day one. - 2 Oct: chat, sent a video of the fault. Told to reset them. Did, no change. - 8 Oct: chat, told "we've escalated your case" (ticket 77120). - 15 Oct: chat, told again it was escalated. Nobody has replied since. What I want: a full refund of EUR 249 and a prepaid return label. Not a replacement, I've lost trust in this model. How firm: polite but serious. This is my last message before I go to my card company.
Steps
Step 1
Write down what happened
What you bought, when, the order number, what went wrong, and every contact you've had with them, with dates and what they said. Rough notes are fine.
Step 2
Say what you want
One outcome: a refund, a repair, a replacement, a credit, or an apology and a fix. Add how firm you want to be and where it's going (email, contact form, letter).
Step 3
Check the facts it lists
The letter puts your dates and numbers in order. Read the timeline and fix anything it got wrong before you send. It only uses what you gave it.
Step 4
Send it and note the deadline
Send it where the company says complaints go, keep a copy, and put the deadline in your calendar. If it passes, you have the follow-up line ready.
What you get
What you put in and what you get out
When to use it
Use it when support has stopped answering, or keeps sending the same template, and you need one clear message that puts the facts in order and asks for something specific by a date.
When to skip it
It doesn't know the consumer law where you live and won't cite rules it can't check, so it asks for an outcome, not a legal remedy. It only uses the facts you give it. For a big claim, an insurance fight or anything heading to court, talk to a consumer advice center or a lawyer.

The mess
€249 headphones, left earcup dead on arrival, three chats, two "we've escalated your case" replies, no refund after 19 days.
Full prompt
strongly-worded.prompt.txt
You write complaints to companies for a customer who wants a problem fixed. The goal is a result (a refund, a repair, a replacement, a credit), not revenge. You write firm, polite, factual messages that are hard to answer with a template.
INPUT
- The company and the channel (email, contact form, letter).
- What was bought or booked, when, the price, and any order or ticket numbers.
- What went wrong, and every contact so far with dates and what the company said.
- The one outcome the person wants, and how firm they want to be.
- Optional: a consumer rule the person has found on an official site, pasted in.
HOW TO WORK
1. Read everything first. Build a timeline of dates and events from the notes.
2. Check the notes for gaps: missing dates, missing order numbers, an unclear ask, more than one ask. List them in a short note before the letter.
3. Pick one main ask. If the person listed several, lead with the one they care about most and mention the others as fallbacks only if they said they'd accept them.
4. Set a deadline. Use 14 days from today unless the person gave one or the problem is urgent. Write it as a date.
5. Write the complaint.
6. Write the follow-up for when the deadline passes.
RULES
- Use only the facts given. Never invent dates, amounts, names, promises or reference numbers.
- Never cite a law, regulation or paragraph unless the person pasted it. Don't claim anything is illegal.
- No threats, no insults, no sarcasm, no capital letters for emphasis. Firm comes from facts and a deadline, not tone.
- Name the next step only if the person mentioned it (card dispute, consumer center, review site), and say it once, calmly.
- Keep the complaint between 150 and 250 words. Short paragraphs. Numbers and dates exactly as given.
- Write in the language the person used unless asked otherwise.

How it works
Complaining well is a skill. Most complaints are either a furious paragraph that's easy to dismiss, or so polite that support closes the ticket with another template. The ones that work are boring in a good way: the facts in order, one clear ask, a date.
This agent writes that message for you. You give it what happened, the dates and what you want, and it turns your notes into a firm, polite complaint that's hard to ignore.
What to paste
The company and where the complaint goes. What you bought or booked, when, the price and the order number. What went wrong, and every contact you've had with them, with dates and what they said. Then the one outcome you want and how firm you want to be.
What you get back
A subject line that says what it's about. A complaint of about 150 to 250 words: what you bought, what went wrong, a dated timeline of what you already tried, the one thing you want, and a deadline as a real date. Then a short follow-up for when the deadline passes, and a checklist of what to attach (receipt, photos, chat logs).
It stays polite and specific. It doesn't threaten, doesn't insult the support person, and doesn't cite laws it can't check. If something in your notes doesn't add up, like a missing date or a vague ask, it tells you before the letter instead of papering over it.
Questions about Strongly Worded
Should I mention consumer law in the letter?
Only if you know the rule that applies to you. The agent won't invent a law or a paragraph number. If you paste the rule from an official consumer site, it will quote it. Without that, a clear timeline, one ask and a deadline usually work better than legal-sounding threats.
What deadline should I give them?
Fourteen days is a common, reasonable choice for a refund or a repair answer. The agent turns it into a real date. If the problem is urgent, like no heating, say so and it will use a shorter one and explain why in the letter.
