One Possible Version
Dear Sir/Madam,
I’m one of your customers, I’m writing to complain about your bad service. I placed an order for a set of Harry Potter Series on your website two weeks ago, but I didn’t receive them until yesterday. And much to my disappointment, the books were so poorly packed up that the cover of one book was torn. To make matters worse, it is not a complete set as I found one book missing.
Therefore, I require that you should apologize to me for your mistake and make up for the loss in time. I trust you will take my complaints seriously and improve your service. Thank you for your time and kind consideration.
Looking forward to your reply as soon as possible.
Yours sincerely,
