Complaint About Poor Service
For bad customer service, delays, or a service not delivered as promised: describe what happened factually, the impact on you, and the remedy you expect. Keep the tone professional and the facts specific.
Faulty or Damaged Product
Returning a defective item? State the product, order number, and purchase date, describe the fault, and request a refund, replacement, or repair. Reference your receipt or order confirmation in the details.
Billing Error or Overcharge
For an incorrect charge or invoice: cite the amount, the date, and what the correct figure should be, and ask for the difference to be refunded or corrected. Clear numbers make billing complaints quick to resolve.
Formal Complaint With a Deadline
When you want a clear response window, the letter requests a resolution within a set period (commonly 14 days). A polite, dated deadline shows you're serious without being aggressive.
A note on your rights
This tool produces a general complaint letter — it is not legal advice. Your statutory rights depend on where you live and what you bought. For the specifics, check official consumer guidance for your country (for example, Citizens Advice in the UK) before quoting any law.
