The service quality in car rental agencies in France depends purely on luck. It all depends on the employee you encounter.

The Hertz staff told us it was just a credit card pre-authorization, but in reality, they charged us the full insurance fee without our understanding of French. Moreover, no matter how we tried to explain later, they refused to refund it.

The car rental company refused to accept insurance from the credit card and kept persuading us to buy their insurance.

It's simple, they just don't like to deal with Chinese people.

Long waiting time aside, they insisted on giving me an upgrade saying my two suitcases wouldn’t fit in the Fiat 500 I originally booked. They wouldn’t even let me check the car. Instead, they forced the upgrade and charged me an extra 25 Euros per day, claiming it was a good discount, which doubled my original cost. I had to accept it because I was in a hurry. I chose to return the car in downtown Paris. The train station is in an underground parking garage, but this was not mentioned on the document. I ended up driving around Paris streets several times.
