Are you really going to blame me?

I'm so disappointed with them. I took a courtesy car on the 21st November, it has scratches all over I showed the attendant as we were doing the check list he ticked those spots where I showed him, on the day of me returning the car they said I'm responsible for those scratches told them they were ticked on the check list to my surprise they said they were ticking for dents and not scratches and I'm going to have to pay for those scratches. I asked the to give me five previous checklists on the car since they are saying I scratched the car they haven't been able to do so. I mean if they are so convinced I scratched the car the least they can do is be transparent with me by providing the history of the car. I'm disappointed at them because its clear they make their profit by reaping people off.
