Contract Cancellation

<p>I sent a cancellation request on my telkom contract. I was supposed to receive a call within 21 days, its been 71 days, and my contract has been post dated to be cancelled on the 30th of November 2016 when it should have been cancelled mid October 2016. I have been charged off contract rates which are 50% higher than what i was paying for. I called to complain and i was told i should have stopped using the allocated data. Telkom failed to cancel my contract when i gave them a notice, and i feel that i should only be paying a prorate for the month of October. I think telkom is deliberately not cancelling contracts to rob people of their hard earned money. Can an inquiry or investigation into Telkom be done!!!</p>
