Dear Sir or Madam,I, as a devoted customer of your online shop, am writing the letter to file my dramatic complaint about the poor quality of your E-book and the poor attitude of your server.(考满分作文网-WWW.SANWEN.COM)The detailed problems are as follows. To begin with, there is something wrong with screen of the E-book, which has been broken deliberately or unintentionally. In addition, it does not work occasionally, which hamper using ordinarily. Most importantly, the product does not comply with your description previously both in style and faculty. Most importantly, servers response of not providing refund and exchange a new one makes me overwhelmed with outrage.I would appreciate it if you could refund or exchange a new one for me. I’m looking forward to your reply at your earliest convenience.Yours sincerelyLi Ming
