Enterprise Charged for damage i did NOT commit naples florida

I had to rent a car due to a car accedent, I picked a car up from one Enterprise location, the associate and I did the PRE-rental walk around and discovered absolutly NO damage. I had the car for about 3-4 weeks, took very good care of it. Returned the car at ANOTHER location that was more convienient. We(associate and I) did the POST rental inspection and discovered a VERY inconspicuous soft dent on the rear right door, no paint damage. This was disputed on the scene with the associate. She assured me that it will probably be overlooked went sent to mechanic. I eventually subsided and figured it may have been a shopping cart. I signed off on the paperwork to continue with my day.

5 weeks later....

I recieve a envelop in the mail from Enterprise Damge Claims department, containing multipule pictures of the Front bumper being pryed appart from the rest of the car by somebody's hand. They were stating that there were damages to "bumper Clips".  There was a list of part numbers, paint numbers, labor hours that followed. All totaling up to around $550. No where in the damage claim was a hint at the "dent" in the door which initailly sent the car to the mechanic.

Enterprise is trying to scam me for damages that I DID NOT COMMIT.

I WILL LAYWER UP.
