Dear Felix
Reluctantly, I am writing for the [ORDINAL, ex. fifth] time regarding malfunction of [PRODUCT (S), ex. your A45 compressor].
[STATE REPAIR HISTORY, ex. As you may recall, the A45 was repaired on four occasions within the last two months.] I have taken the liberty of enclosing a copy of the repair requests and paperwork involved. [STATE NATURE OF MALFUNCTION (S), ex. Again, the compressor ceases to operate within five minutes of starting and emits mass amounts of smoke.]
You are a reasonable person. Surely you can understand that this is not acceptable to us. Since I know of your good reputation for customer satisfaction, however, I’m certain that you will process my request to return [PRODUCT (S), ex. the A45 compressor] at your earliest convenience. [STATE HOW PRODUCT (S) WILL BE RETURNED, ex. I have shipped the compressor and documentation to you via express mail; you should receive it by Thursday.] [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.

Lydia
