填空题
Dear Ms Lu,
Further to your letter of 25 July concerning the delivery of water-damaged computers due to faulty packing, we have arranged for replacements to be delivered on Tuesday, 30 July. Please accept our apology.
To prevent similar problems, we are making every effort to improve our packing design by using waterproof containers instead of the cardboard boxes.
We thank you for your understanding in this matter and hope that the accident will not stop you from ordering from us again.
Sincerely yours,
Zhang Liang
The president of Sales Department in B. B Company
