Telkom stop debiting my account *******ly

I jumped to a R99 a month data special for 12gig/month with Telkom on 12/11/2016. Telkom debited R708 on 27 December 2016 and I thought the extra amount is for admin fees to open the account. In January 2017 Telkom debited R800 from my account. I phoned them to find out what was happening, I was informed that there is R500 airtime that has been included in my package, I informed the Lady that I have never authorized that and that she should cancel it. She told me that she has cancelled it. To my surprise the following month Telkom debited R1200 from my account, I reversed it and made a follow up I was again told that they fixed the problem. What is worse they don't even give the 12 gig that I signed for. I told them to debit my account on the 27th of every month, they debit in any day that they feel like.

This is *****ING. CAN THIS PROBLEM PLEASE BE RESOLVED!!!!!!!!
