Booked with the company. Needed to add a driver because my flight was delayed. Company said they couldn’t addd any drivers. Rather, I would have to cancel the reservation and rebook with them. The agent told me to call back any time after the scheduled pickup time and they will confirm that I did not pick up the original reservation for a full refund. I called back 3 days later and the agent explained it needed to be done within 24 hours. 1. Agent never explained. 2. If the reservation was cancelled, there was no loss from rentalcars.com. No refund issued, paid for 2 bookings.
