I have rented a car through rentalcars.com Booking reference is 719003605 Greenmotion Dubai. Because my creditcard did not work for the deposit - the car was not handed out to me and the booking got cancelled. Greenmotion said I should go to rentalcars.com to get my money back (about 700 US$). Lee Ann Fyrus works for rentalcars in the helpdesk and said that I will not get my money back. She informed me I have to go to the claim department. So finally it looks like the money 700$ is gone and rentalcars has it. And I did not collect a car (which was booked for 17 days !! ) I cannot recommend neither rentalcars.com nor Greenmobile Dubai for car-rentals. Looks like cheating customers in a way
