Letter One

Gentlemen,

We are sorry to have to complain about your usually very fine goods.

The last shipment of 100 dozen blouse(女士衬衣), ordered on March 23rd, is unsatisfactory and we cannot accept it. The collars are noticeably uneven on some of the blouses; and there are open seams(接缝) on many of the sleeves.

We are sure this was just due to carelessness in quality control, and that you will send another shipment of blouses promptly to replace this faulty one.

Faithfully yours,

×××

Letter Two

Dear Sirs,

The machine we bought from you on May 2nd has broken down completely. We have been unable to have it repaired.

Since you have no service center in this territory, we are returning the machine to you via fast freight(快运). We request you send us a new one promptly, as stipulated(规定) in your guarantee.

Faithfully yours,

×××
