Failed to refund me after not releasing car to me

It was horrible service from the 1st call to inquire about a security deposit on a car i wished to hire. When speaking to an agent after being on hold for over 5 minutes I was advised that I could pay it when collecting the car(NO CREDIT CARD WAS MENTIONED). When I arrived at Avis, i was rudely dealt with and was in fact stranded as I had caught a Cab to collect the hire car. I was then informed that I needed a credit card although I had more funds in my account than was required and was prepared to pay the full security deposit. In the end I have still not been refunded my money for the vehicle. When I attempted to make contact Via email, I was systematically answered by a AI bot advising that my claim for a refund has been rejected. This is absolute ******* that a international listed company can ***** from a person in this way. Avis has no shortage of vehicles and most definitely did not lose anything by not hiring me the car, Instead you *****ing snakes took my money. If you think this is how you get business then maybe "takealot" should school you and your all your directors with a customer service module!!!!
