Italy: Rome–Naples–Siena–Florence–Rome

The location was easy to find and there were no lines, which was acceptable. However, my English is not good so I bought the super insurance on Zuzuche and had already paid for it. When we arrived, they handed us a paper and spoke quickly, so the three of us thought it was just the deposit and signed. Later, they gave us another paper indicating the deposit. I immediately called customer service, but the rental company's attitude was very bad, and they said they couldn't refund. They also explained that they don't recognize insurance purchased online.
