RentalCars won't refund even before renting

Well it happened a few months ago, and I learned about HelloPeter.com recently. I'm trying to get help here.<br> <br> I booked a rent car through [URL Removed] and paid in full a few weeks before we actually rented the car which was on the 19th July. We arrived the BidVest office at OR Tambo, and I checked that there was no daily limit of travelling distance. As it turned out, there was a daily limit of 100 km per day, which wouldn't work for us. <br> We asked them to change the condition, or cancel the booking and make another order without daily limit. We were even ready to pay some change fee or cancellation charge. But they said no, because, according to their system, we already rented the car! But we didn't. We were at the office, we even didn't see the car, we were still working on the paper. And the reason that they thought we already rented the car was that it was past the time of \estimated pick up time"on their system.<br> <br> Isn't refund a divine right of customers? In this case"
