Enterprise Rent A Car Bad Service from Enterprise Rent-A-Car, charged me what I didn't do WOODLAND HILLS, California

I needed a spare car for the last weekend, then I used the weekend special to make a reservation from one of this location, 21118 VENTURA BLVD, WOODLAND, HILLS,CA 91364-2103. I have been to this location for about 40-50 times for the past two years, and haven’t got any bad experience so far. People at this place always telling me that they do not care about small damage, that’s why I didn’t check the car carefully, especially the roof. I think no one will check the roof of the car when renting the car. But when I returned it this morning, I was informed that there are dents at the roof, and they will file the damage report. I am so shock about it. I had only drive that car for 23 miles totally, and most of time it just parked at the parking lot. I can’t even see the dents at the first time when I tried to find out about it. I took some photos of it because I want to fight with them. My wife told me that the car rental dealer must just want to collect some money to repair the car. I was just in black luck, because they need someone to pay for it.
