I had a similar issue with SixT rental cars at LAX. They are a rapidly growing but dishonest German rental car company. I was given a car that had damage on the right side door. They told me not to worry about it as it was all in the computer. I told them I wanted documentation of the damage. They said they don’t use forms as it’s all in the computer. I refused the car unless they provided documentation. The finally wrote a description of the damage on my rental form and I had the agent sign it. I videoed the damage with the agent in the picture signing the form.
Two weeks later our credit card was charged 3400 dollars to repair the damage. I sent them a copy of the rental form and they replied it was not valid as there was no damage listed in the computer and I had to pay. I then sent the video and they still were going to charge me until I threatened legal action and contacting the CA attorney general.
Moral of the story, if given a damaged rental car video everything!
