RentalCars.com review: Avoid at all costs.

I booked a car through booking.com that was through National. Turns out the car was actually rented through a third party 'rentalcars.com'. My plans changed and I dropped a 44 day rental off on day 11. They claim there is a no refund policy. However, the policy is unusual and was not listed on the voucher. They claim there is nothing that can be done. I even asked if I could get the car back since I was paying for it and that was not allowed either. They are taking thousands of dollars from me and they claim I cannot get it back. Let this message be a warning to others not NOT use rentalcars.com or booking.com. This cannot be the right way to treat people.
