There is no communication between customer service agents. The guy at the airport was indifferent and showed no consideration for a lady picking up the car. He didn't mention the bank card discount. Without a chat history on WeChat, it would be difficult to prove anything. Two days after renting the car, I wanted to extend the rental. I contacted their customer service online, but it was like the store was closed - no response all day. Luckily, I reached them through the app platform. Otherwise, it would have been a disaster. As fellow Chinese, why make things difficult for each other? This company's prices are not low compared to others. They even asked to switch cars with me, and when I agreed out of goodwill, they turned their back on me. Not all promises made over the phone were kept. So, don't bother being nice to people who won't appreciate it. It's purely a transaction.
