Unhelpful staff and no outcome of the matter.

Have hired a car on the 18 of November 2017 which a deposit was taken from my wife's personal account of R2050.49. The guy that attended to us has said that when the vehicle is returned the deposit will be returned to the account and will take between 7-10 working days. After waiting this period we contacted avis numerous time to query this issue and the answer we keep receiving is that,"we have sent a request to the bank to release the funds". I called again today to receive the same answer and the agent abruptly cut the call thereafter. I understand that avis has requested the bank to release the funds but you have exceeded your return policy and there's no money in the account still. The matter is unresloved! And to have rude and unhelpful staff makes the matter worse. This is not how a business should be treating customers and playing with people's money especially during this time of year.
