ABC just committed what, in my mind, is the mortal sin of taxi companies. Despite having called the night before to make a reservation for an early morning ride to the airport, they called me ten minutes prior to scheduled pickup to let me know that they didn't have any drivers interested in my short 10 to 15 minute ride. I had to scramble to find another cab and barely made my flight. This stressful situation obviously could have been avoided if they would simply have been a little more honest with me the night before. Absolutely horrible customer service.
