1. Pickup store: When I went to pick up the car, there was one customer ahead of me returning a car, and only one staff member available. After waiting for about ten minutes, it was my turn. The staff member took my pickup slip, documents, and credit card, and started entering details into the computer. Then he printed a receipt for €500 along with the contract for me to sign. I double-checked and noticed discrepancies with my order. Upon communication, I discovered he had added insurance without asking. After reprinting the contract, I found he also added navigation. Finally, the contract amount matched, but some other fees were added, which he couldn't explain. I called the rental company’s customer service, and they informed me the taxes had been changed by the rental company. I asked for the original and current amounts, but the customer service said the contract price was packaged and couldn't provide specifics. Confused, I relayed this to the staff member, who said he hadn't altered the taxes and directed me to their manager at the terminal. The manager explained that the fee was a deposit to ensure the fuel tank is full upon return. Finally, I got the car. 2. Dropoff store: The roads around Paris airport are very complicated, and there are no clear return signs. After circling twice without finding the store, I called their number, but no one answered after several automated options. I called the rental company, but the customer service couldn't clearly explain how to find Hertz. Luckily, we had two people, so one stayed with the car while the other walked to the terminal to ask for directions. We eventually found the counter on the first floor. They drew a map, and we finally understood. All companies (including ours) are accessed through the RENT CAR ramp between terminals 2D and 2C, far left on the elevated road. It took us nearly an hour to return the car at the airport.
