Poor customer service and steeling from customers

I have contacted Avis Centurion to get answers and to book a vehicle. The vehicle has been book and I have ask for a specific vehicle. When arriving to collect the rental, I was told that I have been quoted on the cheaper class and that the rental amount is higher and the the deposit is more. I accepted it because I wanted the larger vehicle. After returning the vechle I had to phone to get my final invoice because their online system is not working. They have now processed the total charge and deposit as a payment on my account, no longer just reserved they actually taken the payment. On request when the refund will be done, I was told that it has already been processed on the 4th of October 2025. now 6 days later it is still not in my account. They are saying the bank need to process the payment.

DO NOT DO BUSINESS WITH AVIS, THEY WILL ***** YOU
