When picking up the car, the model we reserved was not available, though that was not the main issue. The main problem was that when picking up the car, it was just left there without any staff to confirm its condition with us. What's worse, when returning the car at the airport, it took three staff members over fifteen minutes to check it, and they claimed there was a small dent on the right door (apologies, but none of the four of us noticed it because we are not professionals!). We drove very carefully and parked the car in a wide spot at the hotel to avoid any potential accidents at night, taking a taxi instead. The rental company said it might have been someone else who caused the damage, yet they still charged us! I would like to ask why no one checked the car with us when we picked it up, but they were so meticulous upon return. It seems intentional to find faults! Moreover, they checked our car very thoroughly, unlike with other cars before and after ours, which were returned quickly. This feels deliberate! We argued for a long time that day, but because our flight was about to take off, we couldn't continue and had to comply. Avis, please reflect deeply on this!
