Initially, the staff strongly recommended a higher-level sports car and falsely claimed that the discounted price included insurance. In the end, the total cost exceeded our budget. Despite repeatedly telling them to stick to the original booking and that we didn't need luggage insurance, they pretended not to understand. As individuals with study abroad experience, we believed we could make our point clear. Eventually, they had another supervisor take over, who fully understood our request, but the final price still included some additional insurance fees, which did not match the total price I had booked. This was very confusing. I had already selected the option for third-party liability insurance at an additional daily cost of 20-30 yuan during the booking process, so the total price should have included it. Why did the final price differ? If that's the case, is there any point in pre-booking? This is completely unreasonable. If there are additional taxes or other fees, it should be displayed at the time of booking. When we arrived at the front desk at the airport, they informed us that certain insurance options were not included. This wasted a lot of time.
