The staff did not explain the documents and vouchers that required our signatures. When we asked about the purpose of the credit card charge, they told us it was a vehicle deposit. Later, we discovered they had charged us for insurance without informing us, even though we had already purchased insurance domestically. They forced us to sign for additional insurance without our knowledge. Before returning the car, we called the store to extend the rental by 2 days, agreeing to pay an extra 100 euros. However, they later charged us over 270 euros. Despite the fuel tank being half empty, they charged us for a full tank. Throughout our inquiries, the rental company made numerous charges, causing significant confusion and loss. After a month of back-and-forth communication, we still haven't received a final response or the promised refund. We are extremely disappointed!
