题目内容：
根据下列材料，请回答题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 ob- vious 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 good- will 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
