The process of picking up the car was extremely slow, even though I had pre-registered online as required. The actual waiting and processing time on the day was three hours. The main reason was the lack of staff, who were also doing multiple tasks, such as answering hotline calls in the middle of helping customers. The handover of the vehicle was rather careless; they started serving the next customer before fully addressing my questions. It was even more frustrating when I was left to inspect the car myself and couldn't find anyone to assist when I had questions. When I asked another staff member for help, they coldly refused, saying they were not familiar with my order and were too busy, and insisted I continue looking for the designated staff without offering to help (e.g., by contacting the assigned personnel).
