Beware of Car Rental Sharks

PLEASE, PLEASE PLEASE do not ever use Car Flex to rent a car. I live in JHB and required to rent a vehicle for 9 days over Easter. I went onto a website looking for best rentals in CT. Innocently and inadvertently I went onto a site which showed the best prices of car rental companies in CT. I chose First Car Rental as they were the cheapest on the list. I booked and had to provide a credit card. To my astonishment , dismay and without any knowledge, I later discovered that on a car rental of R5 200, CAR FLEX debited my credit card and charged an amount of R2 000, for what, I am still shocked. I had not realised that I had booked through a 3rd party in a devious and exhorbitant manner. Be warned, never get caught in the trap of CAR FLEX.
