I rented a car from "ABA rent a car" agency in San Carlos de Bariloche, Argentina. I had to pay in advance for 10 days in order to reserve the car for me. It was promised to me that I would get my money back if I return the car earlier. Eventually I returned the car after 2 days and never got a cent back! ABA simply stole my money! Beware and avoid doing business with them!!
