Worst car rental experience ever, downgraded vehicle and unauthorized charges after returning home!

Terrible, this is the worst rental experience I've had abroad! Booked a BMW 2 Series, got a 1 Series instead. The car size and trunk capacity are completely different, leaving us with no space for our luggage. Their attitude was horrible, claiming they don’t have BMW 2 Series! They demanded 650 euros to switch to a Ford of the same size! It's just a scam! Downgrade the car and then charge extra. Two months after we got back, we were charged over 200 euros again. After multiple communications via the rental platform, they claimed it was for insurance. We had bought full insurance through the rental platform and explicitly declined insurance at pickup, signing no documents. They charged us on the last day before the credit card guarantee expired. Absolutely shameless and garbage service!

The salespeople will deceive you! The salespeople will deceive you! The salespeople will deceive you!

The office is located in the farthest room, probably because its market share isn't high enough. Attitude was okay, and after completing the paperwork, the staff guided us part of the way since we didn't understand the directions to the car. He mentioned that we could return the car without a full tank and that their fuel price was cheaper than gas stations, which wasn’t entirely true. Maybe it’s a little cheaper than the stations near the airport, but I’d recommend filling up before getting to the airport. Diesel in rural areas was only about 1.26 euros per liter. The car was in great condition, a Fiat 500L, which can actually fit four people and two large pieces of luggage.
