Customer Service Department
Dear Sir or Madam，
Sincerely yours， Li Yuan
I am a customer who bought a Nokia 2600 type mobile phone for 2600 Yuan from your company on 2010-9-1. I am afraid I really must complain about the quality of this product.
After using the mobile phone for two days several problems have been found. First, the mobile phone could not send text massages any more. If I sent massages, it would suggest that there were some problems with the phone, which have made a lot of trouble to me. Second, the camera couldn’t work as well as before. As soon as I took pictures, there were no pictures kept in the picture files. This kind of problem caused me a lot of troubles. I have gone to your company to explain the problem twice. But because of some reason, the problem has still not been solved.
I prefer to tell you directly in the hope that you will do something to solve my problem. I will be appreciative if you either make a refund or sent me a replacement.
Thank you for your attention to this matter. I am looking forward to hearing from you in the very near future.
