MTN Customer abuse

For anyone who wants to sign a cell phone or Data contract with MTN, DONT... Once your contract has expired after 24 months and you instruct them to cancel, they often dont. I have a R 96000,00 bill from MTN for data contracts they refuse to cancel and which I have never used. This is against the credit act, but they will still try force you to pay. I have been a customer with MTN for 28 years. So much for looking after their customers. Next step my Lawyer and another network.
