Dear Mr. Reed, This is a response to your request for an explanation of slow payment on our company. The payment is question was due on April 30 and mad on May 1; both of us were out of the country. Neither of us was present when the bill arrived, and in the backlog of work that had accumulated on our return, this bill was overlooked. This, of course, was regrettable, but I ask that you take note of the following: 1. The payment was indeed late, but was made only 4days beyond the thirty day limit. 2. We have done business with you for 8 years, and this is the only instance of a late payment. I trust this addresses your concerns. Please call me if you have any further questions or need additional information. Sincerely yours, Dear Ms. Mable, Our representative, Mr. Martin, has informed me that you are interested in our range of word processing equipment. I am enclosing our current catalogue. In particular, I would draw your attention to model SLX34. Should you require a demonstration of this or any other of our products, we will be pleased to send one of our representatives to visit you when we could discuss your exact requirements. I hope that you will not hesitate to contact me again of you require any further information, or if you wish to arrange a convenient time for a demonstration of our product. Sincerely yours, 本文来源：https://www.wddqw.com/doc/e2345f1804a1b0717ed5ddbb.html
