Complain About Poor Service or a Faulty Product • Example Letters, Plus Guides and Samples
Omit irrelevant details and use firm but respectful language. Communicate facts more than emotions. If this letter does not bring action, assume a stronger but still credible tone in the next one. Send only photocopies of receipts and other documents, and retain all original records.
How to write this complaint letter:
- Tell why it is important that the reader take care of the complaint. Give a full description of your complaint, including relevant dates, verbal exchanges, complete names, actions, amounts, invoice numbers, or previous correspondence.
- State what you expect as a reasonable response. Be firm about any agreed-upon prices, deadlines, guarantees, or services (include copies of such agreements). Assume that your reader will be fair and will take appropriate action, until he or she proves otherwise.
- Close with an expression of confidence or anticipation.
Example Letter #1
Last September we purchased one of your five-gallon water distillers from your Springfield distributor, John Doe. We find now that the holding chamber has a leak where the stainless steel sections come together, and it loses water almost as fast as it distills it.
Since John Doe has moved to another state, I turn to you to honor the lifetime guarantee on this unit. I am returning this part of the distiller for a replacement. Enclosed is a copy of the warranty and my registration number. I understand that I incur no costs with this exchange. I appreciate your service.
Example Letter #2
I have not yet received the refund of $226.98 you promised to send me two weeks ago for the faulty lawn mower. I trust this delay is just an oversight, but I need the refund immediately so I can purchase another machine.
To refresh your memory of the details of my case, I have enclosed copies of my sales receipt and the warranty card. I look forward to receiving the check soon. I need the money by next Monday.
Example Letter #3
The CV joint you recently installed has gone bad in less than two weeks. Since I travel extensively for my work, I need that joint repaired as soon as possible. Your service manager insisted that next Friday is the earliest he can schedule the work. Given that I waited three weeks last time only to have a bad part installed, I think that scheduling the repair work within the next two days is reasonable. I trust that you will agree. I'll call this afternoon to verify the time. Thank you.
