If anyone can remember I posted before our trip as to what would be left in EA at 10:30 pm. Well our flight was delayed and we arrived at 11:40 along with another SW flight. It was a mad dash thru luggage and a run to the EA for intermediate only to find it completely bare. There was only 4, which looked like mini vans to us at the far end. I saw a man with a clip board and asked him which car to take for our rental. He laughed and said right now anything, everything is gone. I asked him again if we could take the vans at the end of the intermediate row, he said yes. Well of course when we got to the window the girl looked surprised that our rate went from $190 to $328. She said its because we took a SUV. Well told her the above story and she tried to fix, by this time cars were lined up, she wrote her name and number on our sheet and said it would be taken care of. It wasn't, charge was the same when we returned, and now the charge is on our card. Customer service reply was, "You should not have taken the SUV", nothing they can do about the rate, but will check to see if the employee remembers anything. So beware do not leave the window until your rate is correct. Will continue to fight this, but it will be my last National Rental if not cleared up.
