Really bad experience with Avis

Defective, damaged, unclean car - Renault Trafic 1. gas/clutch exhaust was coming inside the car. The car was not checked, it was supposed to be fixed first. while driving a smoke was coming from the engine, and was going inside the car. as a result plans were cancelled for the trips with car. 2. the car was damaged, front bumper was about to fall off (see pictures), a lot of big dents and scratches on the car. 3. was not clean at all, as if it was just given to us from previous rent. Bad customer service 1. spent half of the day dialing customer service, dialed 2 for van and trucks and refused to customer service, told us not to call this number, and everyone would refuse service. Finally when managed to call manager was only refunded the days for not using the car and offered no upgrades, or contract cancellation. Worst towing experience: took us 2 hours 1. we could only manage to get Renault towing service the next day and the guy comes out and blames us in French that we ruined the car and we do not know how to drive manual. He did not understand that we were given a car like this in the first place. I was able to get a policeman to explain him that it was not our fault. The only outcome: got refunded the days we did not use the car and a ride to nearby Avis in the railway station. Second car given was fine, and it did not have the above mentioned issue.
