Second review no response from Telkom

I received no response after logging my issue a week ago. I phoned today and they escalated my call. I have now received a message to say my issue has been resolved and I am expected to pay money back over three months which was a error by Telkom. It is quite a large amount that they are expecting me to pay, but the best part is they will not reconnect my wifi until its paid. So I must pay over three months but not have any wifi for three months but I must still pay for the month??? how does this make sense Telkom. My previous review below which was not answered:

Telkom's mistake I have logged a call with Telkom and the service I got was good but I am annoyed that I am now stuck with this issue.

In late November 2017 I phoned Telkom and changed my bank account details. Unfortunately Telkom don't allow the bank to do the switching so I had to phone and do this myself. I made the changes and was assured all was fine. Now I have been suspended becuase of non payment. I have direct debits for a reason, I make sure there is money, I don't check every debit that must come off. I phoned Telkom and it was confirmed that yes my new bank details had been added, but the person who served me at that time did not remove my old bank details. The system was still trying to take money from my old bank account details and not my new details that were on the system.

Of course now this becomes my problem. I have to wait 72 hours to be assisted to arrange a payment plan. Who knows if they will remove the suspension. As far as I am concerned this is a Telkom fault, they should lift it immediately and I think I deserve to be excused for those months or at least give me percent off my bill as they made the mess up.
