Telkom the leech

I have a contract with telkom and until two months ago, I had no issues with them. The issue began when I changed banks. I switched from Capitec to nedbank towards the end of May for personal reasons. I informed Telkom about this switch and I was informed by the consultant that they already ran the debit order so I had to make a manual payment of which I did. At the end of June they didn't deduct any money since they take longer to deduct, I decided to give them a few more day to deduct...still nothing by the 11th of July. I received my monthly statement which had an extra amount of R202. I made a call to their call center and informed the consultant that they still haven't decucted to which she informed me that once telkom makes a deduction and finds no money in my account, it waits for two consecutive payments for it to be able to make a debit order in my account. I understood that although I found it weird. I asked about the extra R202 to which she said that it is the amount charged for May for the debit order bouncing back. I didn't like the fact that I had to pay an extra R202 but I was fine with it just to get this mess sorted out. We agreed that I would make a manual payment and at the end of the month Telkom would be able to deduct from my account. The problem now is that I prepare to go make the payment and to my surprise all of a sudden Telkom was able to make the deduction in my account for more than the agreed amount, mind you it is mid month and schools are reopening. I reverse the amount and I call the call center to give them a piece of my mind. The lady informs me that because I reversed the amount I'll be charged R202 again...like ***? No! This R202 I do not consent with because I never agreed to that amount being decucted hell to my knowledge telkom can't even access my account until I make one last manual payment. Why must I pay extra for their incompetence. What I was told by the first and second consultant don't correlate with what I was told today by this consultant. What we (the consultant and I ) deduced was that I misinformed. I will not pay this extra amount because they didn't train their consultants well. This is bull**** and it must be sorted out. To say I'm disappointed is an understatement. I am beyond angry.
