total incompetance

I've been trying since February to cancel my expired contract. Filled in form at Clearwater Mall, I have a copy. Then phoned customer care, they tell me they escalating it, ha-ha to where into space because obviously your staff where they escalate it don't give a damn useless service. Now I get told that I will be billed for the data on my Samsung tablet which will be loaded tomorrow as it is too late, please check on my call records. This is totally unacceptable, money making racket typical in South Africa, pay pay pay for no service, what can u expect it's Telkom. Please be advised go to any mobile provider except Telkom, nightmare. I'm a pensioner and refuse to pay for what I didnt want. I WANT PAY As U Go can u get it, I will be reversing my debit order at end April, so if u able make a note that I WILL not pay . shocking service been trying to get these *********** people to do something since February. So be warned don't u dare loaf data on my tablet at midnight tonight this contract has expired
