Scheduled a pick up a day ahead for a 5:15 a.m. pickup. Finally at 5:30 we called and we advised that the driver was here at 4:50 a.m., called up and said we cancelled. Let me see, no calls, no missed calls............ Thank you Ace for making a case for Uber. The last thing I want to deal with is a lying company or cab driver. NEVER AGAIN!
