Bank has ****** my money!!!

I failed to pay revolving loan account. Account was handed to Macrobert attorneys. They gave a settlement offer and this was settled in December 2015. I received a settlement letter after many missions as there was miscommunication between standard bank and MacRobert attorneys. They are highly ***********. After paying the settlement amount on 21st December 2015 and receiving the settlement letter I am still debited a random amount of R3519.81 this last Tuesday and then another R2500 last night. I only earn 10000 a month and now am being told they will consider a refund when possible? ??Standard bank is useless and are not helping.. I have no money left till they review their mistake? They are debiting my account for a loan that has already been settled and I must fight for a refund and to get the account closed!<br> I need your help please! This is urgent! <br> <br> Kind regards<br> Lee Erlank
