高一英语作文题目:电子邮件

   Dear Sir，
   I am writing to you for the mobile phone of Dephone-S250 I bought on 20th Apr.2008 at Tele Mall in Wuhan, P.R.China.Ten days after that, it didn't ring and send short messages. Then I took it to the seller, but was told that the model had been sold out and I had to wait at least three months for a new one. Later I went to the repairman. He said since it was a new model in China, it was impossible to fix it without the right spare parts. I was so desperate on hearing that. How can I wait that long? Therefore, I require that you send me a new one of the same model within a month.
   Thank you for your consideration.
   Sincerely yours,
