The merchandise that we ordered from you on March 27th，was delivered on May 17th， which was two days after our sale had ended.  What is most regrettable， is the fact that I believe if we had the merchandise on hand for the sale， we could have sold three or four cases.来源：考试大

　　I understand that you were experiencing some internal problems during this period.  I am， however， unwilling to keep the six cases that were just delivered due to the delay.  Two cases will suffice for now and I would appreciate it if you would have someone call for the remainder and credit my account accordingly.来源：考试大

　　Thank you for your prompt attention to this matter.
