I called the day before to schedule an early morning pick-up. I also called 15 - 20 min prior to the scheduled pick up time to ensure I wouldn't be late for a flight. The car never arrived and I had to urgently scramble to make alternate arrangements before 6AM. When I called to let them know, they were unapologetic and basically just said, "driver's on the way". Do not rely on this company to take promptness seriously.
