I rented a car through them in Colombia. When I arrived to pick it up, the company couldn't release the car to me because I have a passport from one country but a driver's licence from another. There is a mention of having matching ID to pick up the car, but nowhere does it state that that means same country. I've rented all over the world and it has never been a problem before. Alamo was very nice and agreed to waive the cancellation fee that they would normally charge, they put it in writing to Rentalcars.com. Yet Rentalcars refused to return the full amount and made it sound they were doing me a favour by agreeing to refund me part of the rental cost. It took endless emails, first they said I could get the a full refund if Alamo agreed to waive the cancellation fee but they then went back on that and only gave me a partial refund. Terrible customer service. Up until now, I used Rentalcars several times a year, but Never Again! They just steal your money and lie. From now on I rent directly with the rental company.
