Dishonesty and Theft

We have written a review for BUDGET RENT A CAR, but the company hasn't responded to past complaints and since it is in cooperation with Avis, please take note of the below:

My fiance and I needed to rent a car and of course, most companies require the licensed driver to have a credit card, so my fiance was the driver but he didn't have a credit card, and I had the credit card but am not a licensed driver. In light of our situation, I called the company and asked them if I am able to book the car on his name, and pay with my credit card, and they informed that it is possible, as long as I can present the card to them when we pick up the car.

So obviously I booked and payed for the car since they gave me the OK. When we got to the company to pick up the car they informed me that we are now unable to get the car because the credit card is not in my fiance's name. I explained how I called their company and they informed that it was doable, but the lady at the front desk refused us. I asked what of the payment then, because I had already paid for the car and she informed that they would process a refund and it would reflect in my account within 3 to 4 days.

One week has passed and I have not received any payment, I have called them numerous times and emailed them numerous times as well, each time being informed that my refund will be processed. It has been nearly 2 MONTHS and we still haven't received our feedback. This booking was made for the 6th of March, and on that day, they informed me that my refund was being processed.

This company has deducted a big amount from my account, as we all know, renting a car in not just a couple hundred rand, and even though they refused me service, I have not yet received a refund.
