ENTERPRISE RENT-A-CAR FALSE DAMAGE CLAIM GILBERT, Arizona

I rented a car from Enterprise in Gilbert, Arizona during the month of Nov. 2011. This is not my first time renting with them and have been a loyal returning customer for years and I've never had an issue until now. After my car was checked out and damage and gas inspection was approved by Nancy I got a complaint letter from there damage department stating that there was $518.86 worth of damage done to the car. I am furious with this notice, I strongly believe this accusation is FALSE due to the fact that I never made any damages to the vehicle, the Enterprise rental agent(Nancy) inspected the car upon returning it and found no damages or never informed me of any at that time. I believe the damages (if their is any) occured AFTER returning the car and inspection was made and I had already left the business, possibly from drop off point to the companies parking area made by an Enterprise associate. I plan on appealing this accusation and never renting from Enterprise again also never referring potential clients to Enterprise as well if this matter isn't dismissed and I am found not liable for these damages I never made to this vehicle. I am an honest person and excellent driver and would of notified them if I made any damages to their car I rented. I would hope to continue my business with Enterprise so I hope they realize that I am not at fault in this matter. Lets see what happens
