【正确答案】正确答案：Dear Sir/Madam, I bought Pride and Prejudice from online bookstore last Friday, and I received it yesterday. Jane Austen is my favorite writer so I started to read it last night, and unfortunately I found some problem with the book: I ordered a hardback version, but you sent me the paperback! Now I want to mail the book back for a change, and the post charge should be on your side, or you can refund me triple price difference for my lost. I hope you can check my order and contact me as soon as possible for the solution of this problem. Yours, Wang Lin
