Unable to cancel my contract

My contract had exceeded 2 years. I was no longer finding any need to continue with it. I went into telkom at Stadium on main in Claremont in october. They copied my ID and I was told the contract would be cancelled. I was supposed to receive a call from a consultant to verify this. Of course this didnt happen so I returned to the branch one week later and was told, \they no longer handle mobile complaints it must be done online". So I called stating I wanted tbis useless contract cancelled. It was now November and I had already been debited. Again"
