Despite all precautions, I was still charged over 1000 euros for insurance without my knowledge. Firstly, they added an additional driver fee of over 300 euros, and upon returning the car, they had me sign and charged me directly, even using the deposit to cover the insurance costs. It was extremely disappointing to be charged an extra 1000 euros for insurance on top of the full coverage I had already purchased. They even switched the car to a French model.
