Tooranco Rent A Car - Bahrain

I rented a car from tooranco for over 6 months. Always paying on time, and never complaining even after having my first car break down on me within a hour of getting the car. But after returning my car for the last time, they wanted to charge me 50 bd for just a scratch on the bumper which I'm pretty sure was already there. In the end they charged me 30 bd for the scratch. Two thumbs down, I will no longer be a customer to tooranco rent a car.
