　　A Letter of Complaint about a Commodity

　　Dear Sir/Madam, I am writing to inform you of my complaint about the mobile phone I ordered on your shopping web.

　　First, the product was scheduled to arrive last Saturday, but to my disappointment, I did not receive it until this Friday.

　　What is worse, I found that the mobile phone did not meet my order requirement.

　　What I ordered was a black one, but I got a white one.

　　As a matter of fact, the delay of delivery and wrong commodity has caused much inconvenience to me.

　　Your company has always enjoyed an excellent reputation among customers

　　and that is why I decided to make purchase on your shopping web.

　　Here I demand a refund and your explanations for the unpleasant service you have provided.

　　I am looking forward to your prompt reply.

　　Yours sincerely,

　　Li Ming
