A very terrible car rental experience. The return was scheduled for the early morning of the day we were flying back home. When we arrived at the parking lot to return the car, we discovered the car key battery was dead. We contacted the rental company, but since we needed to catch our flight, we couldn't wait for their staff to fix the issue. The rental company instructed us to take a taxi to return the car key to their office. Since the dead car key battery was their fault, we returned the key and left for our flight. Unexpectedly, they maliciously charged us nearly 300 euros, including towing fees, parking fees, and some inexplicable management fees. This rental company already required an excessively high deposit of 2000 euros, which was unreasonable and seemed designed to facilitate these malicious charges.
