Phone repair

I have always received very good service by Cell C but lately I am very disappointed. I upgraded in July and my phone has gone in for twice. The first time it only worked a week. Cell C send it away for repairs and said it could not be fixed and gave me another phone (I am not sure it was a new one because it was only handed to me by the branch sales person and did not came out of a box). My biggest concern is that I have still a year and a half before I can upgrade again, what if the phone gives problems again. It went in for a second time almost 3 weeks ago. I contacted Cell C after a week saying I have not heard anything back. Tuesday I emailed them again regarding the problem and said that I feel that Cell C should give me a new phone and that I can't go on like this. <br> <br> Wednesday I received an email saying that my contract will be cancelled as per my request and that the technical department will phone me. I contacted them and said that I did not give authorisation that my account should be cancelled. The person I spoke to said that someone will call me regarding both matter. I have not receive and email of phone call.<br>
