We spent an hour dealing with insurance upsell due to language barriers and a faulty translator. Initially, they tried to sell me a super insurance package which I declined several times, but the representative kept insisting. I wasn't sure if I misunderstood, so I called Zuzuche's Chinese customer service from the airport. As I suspected, she was still trying to sell the insurance. After confirming with Zuzuche that I didn't need their insurance and that I already had the coverage I required, the issue was resolved. The staff who processed the contract and the two men during car pickup were very helpful. Later, I extended my rental by a few days due to a change in plans. Despite repeatedly confirming with them that the return time was 6 AM, the staff was 30 minutes late. This made me rush between the check-in counter and the car rental office, causing me a lot of stress about missing my flight. Although I was dissatisfied, I still tipped all three staff members.
