Had to leave at 5am to get to the airport. Booked with green cab the night before. They didn't show and when I called, they said they didn't have my reservation. Clearly they have problems with their reservation system, since I'm not the only one this happened to. Unfortunately, when it is at a crazy early hour and you're on a tight deadline, this throws a massive wrench into things. I will never use Green cab again because of this.
The other times I used them before this I had fine, but not great, experiences. Now I prefer badger cab or union cab.
