A non-US resident booked a car for the US (San Diego) and got a confirmation from rentalcars and Hertz. When he tried to pick it up, (it was yesterday, on Dec. 24) he was told that no cars are available for at least the next two days (until Dec. 26; but there is no guarantee). The plan was to leave the city on the 26th.
Any tips on this situation? Rentalcars phone does not work (they're on holiday). Should he just leave the reservation as is (and wait for Rentalcars reply in their operating hours -- at least to get a refund for the car which has not been received) and book through another agency?
Another problem is that there is no availability for Dec. 25-26 directly through the rental websites like Enterprise, Hertz, Alamo, etc. But rentalcars shows availability. If he books with rentalcars again, is it likely that there will be no availability, as in the original case?
