The car model was downgraded without a refund for the price difference. They even said that at my price, it's impossible to rent a BMW (implying that even if they have BMWs, they wouldn't give it to me), and forcibly downgraded me to a Fiat. They pushed insurance hard, claiming the insurance bought on the platform wasn't full coverage (even though I chose the most expensive option on the platform). Their attitude was okay at first, but it changed immediately when I said I wouldn't buy insurance on-site. In the end, I was forced to buy insurance under threats (even though I called the platform's customer service in China for help, they couldn't do much). It felt like the pre-sale, during-sale, and post-sale attitudes were completely different. The experience was terrible, and I won't use Zuzuche again.
