EXTREMELY TERRIBLE SERVICE FROM AVIS SOUTH AFRICA

As a company, we rented a vehicle from Avis Monument Park Krugersdorp. Upon arrival to collect the vehicle, I realized that my driver's license has expired and we therefore had to transfer the vehicle to another driver. The agent at the branch then consulted with his colleagues and someone on the phone from customer service and they said that we cannot transfer the vehicle and that we had to cancel the booking and make a new booking. We then requested the agent to cancel the booking and make a new booking for which we paid upfront. Take note that the exact same vehicle was rented to us on a new booking. Upon request for my refund of the prepaid amount, I was informed that my booking was never cancelled and therefore they cannot refund me. Someone at Avis then cancelled the booking again (it was supposed to be done when we were are the branch). I was then informed that the cancellation was too late and that the refund will not be paid. Following numerous emails back and forth, no one takes responsibility and I have still not received my refund of the rental paid. The most recent communication received was 3 weeks ago where they asked the card number used when making the original payment. I answered them immediately, but have not yet received any further communication.
