I have two complaints: 1. The rental company didn't provide a full-to-full fuel policy as mentioned on the official site. If you want to pick up the car with a full tank, you have to pay for the entire tank of gas. Although you don't need to return it with a full tank, you usually end up with a lot of leftover fuel, which is somewhat unfair to consumers. 2. I didn't use Sesame Credit as a guarantee, so the rental deposit was taken in cash—yes, you read that right, not a credit card hold, but cash paid via WeChat to the rental company's representative. This deposit is refunded only three months after the car is returned (if there are no traffic violations), which poses a financial risk for customers. I wonder if this is common practice in Taiwan or if it was just my experience.
