Contract cancelled please

I am extremely exhausted with the ****pie service I am getting from telkom mobile, I wanted to pay for my service, I called in and the consultant helping me sent me an sms with the account number and ref that I should use. I made the payment and waited for for the 1st to have my service reconnected but nothing. I called back in and was told I was given an incorrect reference number then asked to send to send proof of payment some email to have my payment allocated. It has been 2months but nothing has been done still. Can I have this contract cancelled please.
