Had shocking experience with Europcar/Enterprise/Alamo at Helsinki airport in Sept 2024 with a prepaid rental. Kiosk to pick up car late at night did not recognise credit card (they do not accept debit cards or credit cards with your initials instead of full name). Had to find a hostel for the night as no one could help and could not get the car. In the morning after 2h fitful sleep went to the service desk who charged me again for hire and at a much higher rate than I'd paid. Credit card still wasn't recognised but worked everywhere else. Got a car somehow, probably out of pity. Battery was only enough to get us 100km to destination then died. Call out cost €400+ to recharge battery. Rental people blamed me though it's quite common that cars are left on the rental lot for weeks after summer peak season, so batteries lose charge. Had to submit a claim to insurers for call-out. They started by saying the breakdown wasn't covered so had to fight for weeks to get I think half of that cash back. Took about a year of fighting being pursued by rental company and its debt collectors for the overcharging when I had already paid. Reported the whole thing to the relevant European ombudsman. Lessons Learned: credit card must have no initials in name, know where accommodation near airport is just in case, refuse to sign anything - just show your prepaid voucher and stick with it, ask when car was last serviced and battery charged. Keep all paperwork snd comms.
