Customer Complaint

They gave me a car with a pre existing dent. I couldn't see the dent when I took the car because the car was parked in the dark and the dent was too small to even notice it during the day. When I returned the car the guy that was doing inspection told me the he's sure he has see that dent before but they are going to investigate... I don't even know if they did investigations but at the end they made me to pay for the dent that I am not responsible for.
