[State nature of malfunctions, example: 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 ———– [Products, example: the C45 compressor] at your earliest convenience. [State how products will be returned, example: I have shipped the compressor and documentation to you via express mail; you should receive it latest by ————- (date & day).] [State how you would like credit to be handled, example: Please forward a refund check to us at your earliest convenience.]
