Re: Printer
Dear Mr. Reed,
I am returning my printer to your company"s customer service department because it is not functioning again. I had sent the printer there to get it serviced a month ago and received it a few days later. I changed the printer drum at that time and it was fine for a week after repairs. But again the paper is jammed too often and I can see some lines on the printed page.
The receipt states that it gives a six-month free service guarantee. So I assume that your company will service it without additional charge. If this is not the case, please call me at 365-8975.
Otherwise, I expect that you will return the printer by June 15th. I am including the receipt from the customer service department. I truly appreciate your cooperation in this matter.
Sincerely,
Lauren Butler Why should Mr. Reed telephone Lauren Butler

A.To confirm an order
