*******, *****ing honest hardworking peoples money

I got my November statement from these *****s stating my installment is R1900.74 not a problem with that and I make sure that that is what is available for them due on 30 November. however to my shock they debit R2500+ from my account that was money that had to pay some other account, no heads up nothing, when I called the call center I had to wait 15+min before getting through to someone and when she didn't want to deal with me she transferred me back into the long waiting line to speak to someone else. Not even a we sorry nothing I complained no response at all, but these lot want you to use a debit order all so they can ***** from customers.
