EPIC FAILURE with Telkom's cancellation procedure AGAIN!

I am utterly and completely dissapointed in Telkom's poor service. Two years ago I moved and it took six months and multiple visits to Telkom's offices to cancel my landlines. After having the assistant in store cancel it online and receiving an sms to confirm the cancellation they kept billing me for the next 12 months. Finally I got that sorted. Now I'm in exactly the same position again. On the 1st of January I visited Telkom's offices at Loch Logan to cancel my LTE subscribtion. I live on a farm and don't have access to LTE and the contract had come to an end. The assistant was very helpful and cancelled the subscription. We received an sms to confirm the cancellation. And guess what, again they keep billing me monthly. When I phoned Telkom they have long stories about the cancellation never being activated. I received an sms to confirm it so how is this my problem? Bottom line I will never use Telkom's services ever again. They are money grabbers that don't adhere to their own systems and policies and always blame their mistakes on their clients. I'm Done!
