They charge me 161 dollar for refueling with high price when they told me when i receive the car the rate will be normal same station price

Nothing

The queue time was very long, there were no self-service machines, and it took about forty minutes to wait in line. Additionally, I had already chosen and fully paid for insurance on the rental car app, but was asked to add more insurance when picking up the car. They mentioned something about California law, but the Mexican accent was very strong and I didn't fully understand. They charged an additional $25 per day.

The processing speed is too slow

Despite having many Chinese customers, there isn't a single Chinese-speaking staff member.

The tire was deflated and I needed to pump it 3 times then they exchanged the car for me. It caused some inconvenience for me.
