Dear Sir/Madam,

    I'm one of your customer. I ordered a set of books on your website two weeks ago, but I didn't received it until yesterday. And much to my disappointment, the books were too poorly packed up that the cover of one book were torn. To make matters worse, it is not a complete set, as I found one book missed.

    I'm sorry to have received such poorly service, and I believe I have every right ask you to deal with this problem. I hope you either return my money back or deliver a new set of books to me. Beside, I'd like to be informed of the process of your deal with my complaint.

    I'm looking forward to your reply.
