Unnecessary and unjustifiable blame on returning the car

Overall my experience was good, however when I returned the car, it was not checked by the staff and after I left the airport I received a phone call from the Budget staff telling me that I had damaged the car. They wanted to keep my deposit and I had to argue to get them to accept that I had not damaged the car. This was the most stressful part of the experience, especially as I could not check whether they had debited my account or not until I came back to the UK. Fortunately, they had not.
