SIXT staff, knowing that we bought Trip.com full insurance, is still selling their insurance again and again; After the insurance sales were unsuccessful, we said that the car we booked was gone, and if we wanted to put down three boxes, we had to upgrade the vehicle, and there was no explanation for the total price that needed to be increased. We only said the single-day price, which made us mistakenly think it was the total price. Fortunately, we looked carefully when confirming the order. Biran was fooled. After we resolutely refused, we finally gave the car we can use without adding any fees. When you rent a car, beware of the fooling of the car dealership staff, encounter problems, and find Trip.com customer service.
