Dear [NAME, ex. Link Building],

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.]  I therefore request repairs to be made under warranty #[WARRANTY NUMBER], a copy of which is enclosed.  If a repair is not possible, I hope that you may send me a replacement.

Please contact me at XXX-XXXX if there are any concerns.

Sincerely,

[YOUR NAME, ex. Jill Jones]
