1. There were too few staff members at the pickup location, and the line was extremely long, taking more than an hour to get through. 2. We reserved a car for 9 AM, but when it was finally our turn, they said there were no cars available and told us to wait without indicating how long it would take. We have rented cars through this platform many times and have never encountered such a situation before. 3. The contract we received from the platform stated 'zero payment at the store,' but the car rental company demanded additional fees. Due to language barriers, we had to go back and forth with the platform for a long time to resolve the issue, wasting a lot of time.
