When picking up the car, the customer service first tried to upsell insurance, which surprised us. We refused. During the paperwork and signing process, we noticed the price differed from what was shown on the initial booking. We asked the staff to check our booking, but she said she couldn't understand it. We asked her to get a Chinese-speaking customer service representative, but there was none available. She acted arrogantly and unhelpfully, so eventually, we wrote on the form that communication was impossible, signed it, and took the car.
