A travel agent booked a car for me from RentalCars.com as part of a holiday and I wasn't able to collect the car through ill health. But Rental Cars charged my credit card for the whole 16 days rental even though I didn't take a car out. Then when I disputed it with the credit card company, Rental Cars told outright lies to the c/c company saying I took a car out on a certain date and returned it on a certain date. The c/c company took the word of Rental Cars even though they haven't got my signature and there is nothing I can do.
