Rental cars.com is a ****ii

Would like to warn everyone that Rentalcars.com is a ****. I was ****ed R306.29 today. I made a booking and there was no indication that a credit card is a core requirement for hiring. When I found out, it was too late and a payment was already made. I then immediately cancelled the booking and requested a refund. Unfortunately no refund was made. My money went down the drain. I Warn people, watch! Rentalcars.com!. These guys are pure *********. What kind of a company that does not refund its customers? It's a pure ****. I don't want people to fall for victim. Watch out Rentalcars.com.
