Dear Felix
Enclosed, please find [PRODUCT (S), ex. your A45 compressor], which we purchased on [DATE, ex. June 1, 1998] (a copy of the sales receipt is enclosed). After limited use, I’m afraid that it has unexpectedly failed. [STATE NATURE OF MALFUNCTION (S), ex. Although the compressor does begin to operate upon starting, it ceases operation within five minutes and emits mass amounts of smoke.]
Since I know of your good reputation for customer satisfaction, I am confident you will repair the item {s} for me or issue me a replacement, as you deem necessary.
Please contact me at XXX-XX-XX if there are any concerns.
Regards
Lydia
