Keeping MY money - Please pay it Back

On the 21st of December I made a mistake of paying off my loan. As an honest mistake I paid the total amount owing instead of the settlement amount. Which meant I over paid the Loan by R22K. I immediately call and spoke to someone about the mistake and that I needed the payment to be reversed or to have the extra monies returned to my account. I was advised that I needed to wait 24hours until everything had cleared. Being on holiday I thought it should all clear up by the time I get back from my holiday. On the 6th January I received my statement from DirectAxis which clearly shows an overpayment of around R22k I called to ask what the delay was in getting my money back. I was told to show proof of payment (strange as your Invoice clearly shows a payment and over payment). So I sent back their statement with a screen shot of my payment, 9 January. A week later I hear nothing so I email, apparently Not good enough they need Proof. So I send proof on the 16th January. Oh, and then guess what just happened, my account was debited this month for a payment, 20 January. So now they owe me around R24k... (Or are they going to make me pay fees and more fees to squeeze all the money they can out of me.

Every time I have spoken to someone in the call center, my frustration gets the better of me as No one can assist, its like talking to a robot. They will not put you through to a manager or supervisor.

DirectAxis can give you a loan within 12hours. But it just seems that if you over pay it take forever to get you money back.

Maybe if I apply for another loan for R24k I can get my money back in 12 hours.

What do you think? I think I will never ever take a loan from them ever again.
