Dear Mr/Ms,
Last Friday, when we were discussing the problems of defective suggested that I simply mail you a report each month on the number of return by customers rather than send the defective containers to you.
I plan to put this into effect at once. But, I first want to make sure that I understand you correctly. If I don't hear from you within the coming week, I'll assume that you approve.
Yours faithfully
尊敬的先生/小姐：
上週五，我們討論了次品集裝箱的.問題，你建議我只需把顧客每月退回的次品集裝箱的數量寫個報告給你，而不是直接退集裝箱。
我計劃立即付諸現實。但我想確認我理解正確，到下週為止，如我不能收到你的來信，我即認為你沒有異議。
你誠摯的.
