In 2004, 5 of us rented a car from National/CITER at CDG for 5 days. On the day of the car return, we had an early flight to Cologne, and got to CDG about 6:00 AM. There was no attendant at the National/CITER booth - it was dark and locked - so I filled out the after-hours car return form and dropped it and the keys in the drop box. (The National/CITER web page said that the office would be attended at that hour.)
On my return home several weeks later, I found a letter from National/CITER telling me that: 1.) the car was in an accident and sustained damage during my rental, 2.) I need to fill out and return the accident report form 3.) I am responsible for the damages (I waived CDW, using my Visa card coverage.) Of course, all of this was bogus. The car had damage when I rented it, which I photographed. I sent them a registered letter denying their allegations and refusing to fill out the form or pay damages. I told them I had photographs of the car.
National/CITER then charged my Visa card; I disputed the charge with Visa, National failed to respond to the dispute, and Visa denied the charge from National. I cancelled my Visa card and got one with a new number. TWO YEARS LATER, National sent me another letter, saying that I'd changed my credit card number and they couldn't charge my account for the damages, and would initiate legal proceedings unless I paid up. I had a lawyer-friend respond at that point, and have heard nothing since.
So my question is, when I return to France as I hope to, will customs pull me aside and cart me off to jail?
(BTW, this same shenanigan was pulled by National at Frankfurt airport in 2001. When I declined to pay for the alleged damages, they dropped it immediately. Of course, I have not, and will never rent from National again.)
