The customer service at night only speaks French, no English. They said they would call me back after our conversation, but I never received a call all night. The customer service experience was poor. Returning the car at Paris airport was very complicated. It is recommended to communicate the complexity of returning the car in advance and provide multiple reminders. Without these, it would be almost impossible to return the car smoothly. Fortunately, I went to return the car ahead of time; otherwise, I might have missed my flight back home. It took three whole hours to find the car return location at the airport — a tough experience. I strongly suggest optimizing this process!
