Milan to Florence

We told them we had paid in full, but the contract still showed three charges: a basic package fee, a snow chain fee, and some departure fee (all in Italian, no English provided), totaling $147. We refused to sign and communicated that all fees were paid in China, and the weather was good, so snow chains weren't needed. They tried to intimidate us by saying the police would check. To give them face, we conceded to the snow chain fee, but they still listed the other two fees, promising a refund after the car was returned. Despite calling for help from ZUZUCHE, which confirmed the same outcome, the whole process took nearly two hours. The car has now been returned, and we don’t know if we can get the other two fees, over $100, refunded. The drop-off location was unmanned except for the car receiver, who told us to contact the store.
