Dear ——— [Name],
Enclosed, please find your —————- [Product], which we purchased on ———– [Date] (a copy of the sales receipt is enclosed). After limited use, I’m afraid that it has unexpectedly failed.

Since I know of your good reputation for customer satisfaction, I am confident you will repair the product for me or issue me a replacement, as you deem necessary.
Please contact me at ——————- if there are any concerns.
Thanking you,
