Picking up the car was quite complicated. First, they didn't have the car model we booked and kept pushing us to upgrade. The rental company even had a Chinese-speaking person call us to persuade us to upgrade. After we insisted on not upgrading, they initially said there were no cars and we'd have to wait 30 minutes. I agreed to wait, but then the customer service representative disappeared. After half an hour, they still hadn't returned, so we had to find another representative to finally get the keys. When we went to the parking lot to pick up the car, the attendant wasn't there either. We waited around 20 minutes without seeing anyone. Since we were in a hurry, we inspected the car ourselves and left as there were no issues.
