Dear Sirs, This is the third month running that your delivery has been late in arriving. Our current order for stationery is already five days overdue. We have a number of valued customers who are being put to some inconvenience. There seems to be no obvious reason why your normally prompt deliveries should become so unreliable. I would be obliged if you would look into this matter as soon as possible. Ours is a small family business in a very parochial (狭小的) area. We depend very much upon the goodwill of our customers. I' m sure you will appreciate the importance of this matter being cleared up at your easiest convenience. Yours faithfully, Grayson Brown 1) Mr. Brown writes to complain about 1 of the ordered goods. 2) His order for stationery has already been late for 2 when this letter is being written. 3) Mr. Brown feels it a pity that the 3 deliveries have become so unreliable. 4) According to Mr. Brown, this incident has caused 4 to his customers, upon whose 5 his small family-run business depends.
