STAY AWAY unless you want to be double charged for your car rental!
We ordered a car through Rentalcars.com & paid in full in advance. After we came back from our vacation we find another (larger) charge on our credit card, this time from Budget.
We contacted Rentalcards customer service: Once they say this kind of double charge is a known fraud. Another time they say that the charge is for insurance (we took only 3rd party insurance and this charge wasn't for that). Once again they say it's not us - contact Visa (who say contact Rentalcars...) Every time there's a different story.
Bottom line is we rented through Rentalcars and if Budget double dip, they are the one who should protect their customers from that. They gave us the run around for a few months and bottom line say - Sorry. We really understand your point but you won't get your money back... STAY AWAY unless you like unwelcomed surprises!
