Telkom Debiting money from my Bank account without my permition

I have currently been trying to sort out an issue with Telkom (Case: ********** 8) where they messed up and did not debit my account for the past few months. They admitted that it was their mistake. After speaking to call centre agents who were extremely unfriendly and lacked the ability to solve any problem, I was told that someone will call my back to discuss possible payments.

This morning the full amount that they did not debit from my account over the past few months was taken from my account without my permission and especially after I had made it clear that I do not want the amount debited from my account.

This is not the first time I have had major service delivery problems from Telkom and have had to deal with the incompetency of their staff.

Anyone considering using Telkom please don't!!! It has been the worst decision that I have ever made.
