Cancellation of contract resulted in *****

We tried to cancel my mother in law's contract with MTN. We sent emails to [Email Removed] as MTN advised us to do. for more than a month there was communication up and down about the cancellation. When the contract was supposed to be cancelled, we went to MTN Clearwater where we were told the contract has not been cancelled. The assistant then sent a request from her terminal to cancel the contract. A month later it still has not been done. I sent some more emails to MTN Retentions where I was told the contract only expires in November 2017. Someone had renewed the contract. I asked for the signed document as we did not request this. NO response from MTN. We went to MTN in Northgate to find out the contract was renewed at MTN Carlton Centre. The renewal brought my mother in law a R 640.00 bill per month for an IPhone 6 that was given to someone. I am still waiting for the signed documents. We were told to go to the police and do an affidavit before they were prepared to do anything. We did the affidavit and the store attendant loaded the information. The contract should have been cancelled by 20 October 2015 but because of MTN staff pathetic service we still have issues.
