The rental store was deceptive. My bill at the store was over 1,200 euros, whereas I had already paid more than 500 euros online. I repeatedly confirmed that I had already purchased insurance and did not need additional coverage. The store staff, however, slyly insisted that the extra 700 euros was just a deposit and would be refunded if there were no issues. When returning the car, they claimed I had used the full insurance and signed the contract, so the order was closed and nothing could be done. This is not my first time renting a car in Italy, but it’s the first time I've encountered such a deceptive mandatory insurance practice. This is commercial fraud and I'm very upset, currently negotiating with the rental platform.
