Capitec ensuring ******* keeps my hard earned money

We paid an invoice to hire a car from a company going by the name of Easy Rental Car Hire, only to find out that it was a ****. Capitec is refusing to do anything unless I can provide them with an avidavit and a POP - the payment came from a Capitec account so why do I need this. Chances are, I will never ever get my R8000.00 back as Capitec is prolonging the process. What steps does this bank even take to ensure that the account number does in fact belong to the beneficiary information provided. How will Capitec ensure, that I, their customer get my hard earned money back to me?
