【正确答案】Dear Mr.Manager,
I am writing to express my dissatisfaction with the steam iron I bought from your department store on July 6,2009.
To my great disappointment, when I took it back home and started to use it to iron my silk skirt, the plastic outer casing suddenly broke in the middle and water came out from the fissure. This new product turned out to be completely useless after its first trial. It is supposed to be a matter of quality. As I am an old customer of your store, this matter really shocked me and I'm afraid it reflected shame on your company.
I shall appreciate it very much if you will replace my steam iron with a new one as soon as possible.
Sincerely yours,
Li Ming
