Worst cellular network ever

Telkom consistently and purposefully bills incorrectly, even after you have proved that you paid your account they refuse . I have never had such a bad experience with a cellullar network ever. Firstly, I have been trying to cancel my contract since September 2017, was a 24month contact that was supposed to end May 2017. I filled out all the required paperwork (should take only 30 days they said) but still nothing to date. Instead I keep getting calls trying to upgrade my contract. Then, they started billing me incorrectly, adding previous months amounts when you have paid the amount. They suspended my phone (after paying timeously). Then, after taking weeks to resolve the issue (I had to send proof of payment, bank statements to like 10 agents) they still send you bills with the same amount convincing you that you have not paid. Threatening more suspension, even credit bureu listings, and sending my account to collections. If that's not daylight *****, I dont know what is. They might seem cheap, but never, ever get a contract phone with them. Its a trap, you will never get out.
