Despicable Telkom and incompetency at its best

My contract with telkom mobile had run its course last year. Prior to finalisation, I contacted the service provider to inform the representative that my mobile had been ****** and although I no longer had possession thereof, I would continue to pay for the contract but would like for it to be cancelled as soon as the contract ends. This was confirmed by the person on the other end of the line. To date, however, and ample calls, emails and visits to the store, nothing has been done and it seems nobody knows what is happening with regard to the contract held. Each time I make contact I am told to something different. Money is still being deducted from my account and I have just about had enough of this putrid "non" service provider.
