They kept pushing insurance and the cross-border fee was twice the suggested price. There was no personnel for vehicle handover, the vehicle provided wasn't the one reserved, and it had multiple noticeable scratches that weren't marked. We had to go back to the rental place, wasting a lot of time. There was a mileage limit that wasn't mentioned, and there was no mutual verification of the mileage data. The charge for excess mileage should be communicated and signed off in advance. There was no mileage check when returning the car either. The deposit has not been released two weeks after returning the car, and there are unclear charges. The responsibilities are not clearly defined, making the customer very dissatisfied. Why is the cross-border fee so expensive without a clear standard?
