Telkom - Ongoing poor Service

I published a review for poor service last week. I received my account this week and even though I said the upgrade should be cancelled, Telkom went ahead and upgraded my subscription. When you dial into the contact centre number, you only have electronic options. You cannot speak to a human. Pathetic. I also requested my banking details to be changed. I had no response to my e-mail. This month my subscription fee will not be paid as my incorrect banking details will refuse payment.
