My package never came and support keeps saying wait. I’m tired of this. I want my money back. Order A12345. It was supposed to be here days ago.
Subject: Request for Refund — Order #A12345 (Delayed Delivery)
Hello [Customer Support Team],
I’m writing to file a complaint regarding Order #A12345. I placed the order on Jan 10 with 2-day shipping and the package was expected on Jan 12. As of Jan 18, the order has not been delivered and the tracking information has not updated since Jan 11.
I contacted support on Jan 15 and was advised to wait 48 hours, but there has been no change. This delay has caused inconvenience and I no longer need the item.
Requested resolution: Please issue a full refund to the original payment method. If you need any additional information, I can provide order confirmation and tracking screenshots.
Please respond within 7 days with confirmation of the refund and next steps.
Thank you, [Your Name]

Pro Tips for Better Results
Get the most out of the AI Complaint Letter Generator with these expert tips.
Add proof to speed up refunds
Mention photos, screenshots, receipts, tracking pages, or chat transcripts you can provide. Referencing evidence often reduces follow-up questions.
Be specific about what you want
State the exact outcome (full refund, replacement shipment, billing reversal) and include a reasonable response deadline to encourage timely action.
Keep it factual and chronological
A simple timeline (order date → expected date → what happened → support contacted) makes your complaint easier to verify and resolve.
Use escalation only when necessary
Start polite, then move to firm or escalation if you don’t get a response. Professional persistence usually performs better than hostility.
Who Is This For?
Trusted by millions of students, writers, and professionals worldwide.
Write a complaint letter that actually gets a response
Most people don’t lose refunds because they’re “wrong”. They lose refunds because the message is vague, emotional, or missing the boring details support teams need to act.
A good complaint letter is basically a tiny case file. Clear timeline. Clear request. And a reasonable deadline so it doesn’t drag on forever.
That’s exactly what this AI Complaint Letter Generator helps you produce. You type what happened. Pick a tone. Choose what you want back. Then you get a ready to send email or letter that reads like a calm, organized human wrote it.
What makes an effective complaint email (and why most fail)
Here’s what typically goes wrong:
- No order number, invoice number, date, or tracking reference
- The request is fuzzy: “Please fix this” instead of “Full refund to original payment method”
- The message jumps around, so the agent can’t verify anything fast
- It’s angry in a way that triggers defensiveness, not action
And here’s what works better:
- A simple timeline: ordered, expected delivery, what happened, what you already tried
- The impact in one sentence (keep it real, not dramatic)
- One clear resolution request
- A response deadline, usually 5 to 10 business days
What to include in your complaint letter (quick checklist)
If you want the generator to produce a stronger letter, paste these details into the “What happened?” box when you have them:
- Order number, invoice number, booking reference, or account ID
- Purchase date and expected delivery or service date
- What arrived (or didn’t), what was defective, what was charged incorrectly
- Tracking link status or relevant timestamps
- Previous contact attempts (ticket ID, chat date, who you spoke with)
- The exact resolution you want: refund, replacement, repair, cancellation confirmation
- Proof you can provide: photos, screenshots, receipts, chat transcripts
Even if you don’t have everything, include what you do have. The tool will structure it.
Pick the right tone: polite vs firm vs escalation
Tone is strategy, not personality.
Polite is best when you think it’s a normal mistake and you just want a quick fix.
Firm is for when you already tried once, or the issue is clearly on their side, and you need the message to land.
Escalation is for no response, repeated stalling, or when you need a manager level review. It stays professional, but it stops being “friendly”.
If you’re unsure, start polite. You can always resend a firmer version later.

Complaint letter vs chargeback vs legal threat (what to do first)
In most cases, a strong written complaint solves the problem faster than jumping straight to a dispute.
A practical order that works:
- Send a clear complaint letter with your evidence and a deadline
- Escalate to a manager if you don’t get a real answer
- If you paid by card and they still ignore you, consider a payment dispute with documentation
- For serious losses or legal issues, get qualified legal advice
This tool helps with step 1 and step 2. Clear writing. Clean structure. Better odds.
