Two months of trying to cancel my mobile contract

My mobile contract expired on the 19th of October. I started a month before calling the call centre trying to ensure that they do not charge me for another month. So as expected they charged me for another month without canceling the contract.<br> <br> I called them every two days for two months now and the contract is still not cancelled. The call centre says that cannot speak to their retentions department and they will send and email and someone from retentions will call me back. No one has called me back! For two months!<br> <br> They say they have had a system issue since the 19th of October and that's why they can't cancel the contract which is utter nonsense.<br> <br> Never ever ever do do business with Telkom if you can help it!
