Unfair deposit and cancelation fee

I wish I could give them negative stars. They conveniently hide the R13 500 deposit on with fine print on their T and Cs one has to pay before picking a rental. This is why they require a payment before you pick up the car because they know that's when most people find out of the R13 500 deposit and will cancel and be penalized 3 day booking penalty. Under handed tactics specialists. I will never ever use these people again. It was my first and last time. Please don't make that mistake.
