This past March we selected and prepaid for a compact car with a standard transmission with Europcar through Autoeurope. We have done this for years and never had a problem until last month. When we went to retrieve our car the young lady behind the desk disregarded my prepaid voucher, upgraded us to an automatic Audi A3, and charged us for the upgrade. I have read several warning post posted on online bulletin boards, but paid no attention because we have always received excellent service from this location. They were extremely slow and we were in a hurry. I signed the contract and they gave me a copy. I didn't realize they gave me a blank copy until a few days later. I received an email from my credit card company indicating a new charge from Europcar. It was then we discovered the upgrade charges. I called Autoeurope, explained the situation, and they advised me to wait until we return home to file a complaint if the charge did not disappear. Well, it didn't disappear so we filed a complaint with Autoeurope. We also disputed the charge on our credit card. The issue hasn't been resolved, but next year we won't be picking up our car from Stazione Termini. I take responsibility for my dumbness for not catching this scam at the station, so I hope this will alert people to take their car from another location.
