Dear Mr. Chang：
On September 10， our order for 280 women's cotton sweaters was duly received， but we regret to say that 40 cotton sweaters in white color were seriously soiled.
We had the case investigated immediately， and the result shows the damage was due to improper packing， for which the suppliers are definitely responsible.
Needless to say， we have suffered a great loss from this， as we cannot sell the sweaters in this condition to our customers. We ask you to conduct investigation at your end and reply to us.
Sincerely yours，
Li Ming
