We weren't able to pick up the car from Rome airport because we only had Amex and a debit card. We'd already paid our deposit using Amex with Holiday Autos, and it wasn't made clear to us that we might require a different card for the pick-up. The car hire company (Goldcar) asked us to call Holiday Autos in order to transfer the booking to another company within the airport, the majority of which accepted either debit or Amex. Holiday Autos refused to do this, and declared us a "no-show". They then hung-up when we asked for a refund. We were left stranded at the airport until we were able to arrange alternative travel to our destination, and missed much of the wedding we had traveled to Italy to attend.
