BAD SERVICE FROM TELKOM

I have been trying to cancel my contract as the 2years has lapsed however since the 8th of August when l made my initial call to cancel telkom has been giving me the run around. I tried to get assistance from their twitter page but they just ignore my messages.

3 of their consultants have failed to cancel the contract and they keep insisting that only the IT department can cancel it however it has been over a month and still no one has communicated with me to confirm that the IT department has cancelled the contract.
