Rentalcars.com are crooks

Rentalcars.com are a bunch of crooks! I rented a car and stated that I land in Cape Town international airport at 20:00pm. I rented Woodford through rental cars.com. When I got to the airport I was told that Woodford closed at 19:00pm. And hour before I was supposed to pick up the car. I called Woodford emergency line and the guy confirmed that they closed at 19pm and that the money was not paid into Woodford yet so rentalcars.com will refund me. It has been 5month of me trying to get my refund from rentalcars.com and they refuse to refund me saying I was at the airport at 21:00. Only because I finally got a hold of them at 21:00 after thrifty helped me get hold of them. Moreover Woodford closed at 19:00 anyway so even if I was there at 19:10pm I would have still not found them. They refuse to refund me.
