I rented a car from Budget/Avis Rent a Car in Helsinki. When I returned the car the overweight fellow at the check in and I went around the car and confirmed there was no damage. I received a paper with the total charges for the rental car )just the rental charge nothing more) and boarded the aircraft. I am positive there was no damage on the car! When I got my mastercard bill, there was an additional charge of 843. Euros on the bill. I called Avis/Budget customer service, they said I damaged the car. I knew that was untrue, both my wife and I were present when the overweight 20 something man and I went around the car to check. But customer service said there was nothing I could do about it because it was already charged to the card. I have insurance with my credit card, and so it will not cost me anything, but that is not the point. I know they have cheated. I do not want them to get away with this. read more
