Inferior product and poor service

I have been a long standing customer for the past few years. I have purchased another contract in August and have had the most dismal experience. The cellular phone that I purchased on the 5th of August did not have network after 3 days and my attempts to rectify this by taking the phone back to Telkom was unsuccessful as both the Chatsworth and pavilion branches did changed the SIM card as they said it was damaged. A week passed and then when I returned to the Chatsworth branch, they said the phone was out of warrantee. I feel that I was short changed by being stalled until the first 7 Days had passed, hence the warrantee due date expired. The Chatsworth branch then sent the phone for repairs to gauteng. Then I received messages saying that I would have to pay R1800 approximately for the repairs of the phone which I was furious with. I told the staff at the Chatsworth branch that I would not pay a cent as it is their problem. Then I was told to pay R180 approximately for delivery of the phone from gauteng to durban. However the phone would return to me faulty and there is nothing more that can be done. I have left several messages with the Chatsworth staff for management to contact me but yet again, no response. I even asked for the area managers details however was told that she was also the manager of the Chatsworth branch. Poor or no communication has left me a frustrated customer. My contract which is pending for renewal ( ********** 812), I have made a decision to not renew with Telkom. Please can someone urgently contact me. I have been paying for this contract since August and did not have the handset. I would like my contract to be terminated.
