Dear Felix
After limited use of your [PRODUCT (S), ex. A45 compressor], which we purchased on [DATE, ex. June 1, 1998] (a copy of the sales receipt is enclosed), 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 regret that we are unable to bear the delays involved in repairing or replacing the product {s}. Since I know of your good reputation for customer satisfaction, however, I am confident you will process our return at your earliest convenience. [STATE HOW PRODUCT (S) WILL BE RETURNED, ex. I will immediately ship the compressor and documentation to you via express mail.] [STATE HOW YOU WOULD LIKE CREDIT TO BE HANDLED, ex. Please forward a refund check to us at your earliest convenience.]
As I am certain that this malfunction is not characteristic of the high quality of your products, I look forward to the possibility of doing business with you in the future.
Regards
Lydia
