Worst rental ever! Will never go back

We called and went immediately to the exact pickup stop and sat within 10 feet of the sign for pickup. The pickup van never came. I called and they said that the van had broken down and then another van would be there in 10 minutes. No van appeared. I called again after 20 minutes and they said a van would be there within 10 minutes. No van appeared after 20 minutes. I called again and rechecked that we are at the correct place and they said a van would be there in 10 minutes. No van appeared and within 20 minutes I called again but they only had an answering machine. I continue to call until midnight and we finally left and got a car with no problem from thrifty Rent-A-Car right inside the airport.
