I feel I've been scammed by a car rental company - on return of the car they 'found' damage (scrape on the underside of the bumper) that I'm quite sure I didn't cause (didn't have any bumps or scrapes during the week), however it wasn't marked up on my rental agreement. I checked all the interior and exterior on pick-up and rental but not under the bumper - had never thought of doing so. I actually had strong 'scam' vibes immediately upon return when the rental person checked it and made a beeline for that part of the car.
I did not take their full insurance as haven't normally had problems with car rental in the past. Do I have any recourse? Anyone else had a similar experience?
