EXTREMELY POOR CANCELLATIONS DEPT

My contract is supposed to end on the 6th of January. I have tried numerous times to call the complaints department, this number does not work and it's an endless loop of verifying your details only to be put through to the customer care dept again. I cancelled my contract the first time in december and since then i have been called by cell c to confirm my cancellation and been told that it has been cancelled. This will be the second time i am dealing with cancelling a cell c contract and i will most definitely never take out a contract again, because they have managed to con me out of at least two extra month's payments because of poor service. The only way to get their attention is going on hellopeter.
