"Yeah your Kayak reservation means nothing", the tired clerk said. After having called Kayak, who routed me to a Priceline number, who routed me to a national Enterprise number, to confirm there was a car available, an Indian call center rep cheerily told me "of course sir, they have plenty of cars, rest assured your reservation is confirmed". So I flew into Shreveport and when I arrived, I waited with other tired travelers about 40 minutes past opening until the clerk showed up (I was first in line). She said there were no cars available. That "Oh you booked with Kayak? Yeah they have no idea if we have cars or not." I asked when she would have cars available. She said maybe in a week, but maybe not, they'd been fully booked for weeks. I asked how I should have booked the car. She said there's no good way to do it, but that I could try calling the phone at the desk. I asked for the number. She said she wasn't allowed to give it out. What??? I will NEVER use Kayak again. And I probably won't do Enterprise/National.
