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 inconveniences. 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 (牧区的, 偏狭的) area. We depend very much upon the goodwill of our customers. I will be grateful if you could clear this matter up at your earliest conveniences.
Yours faithfully,
Grayson Thomas
