I can top that!  Monday night I called and set up an appointment with a very high visibility provider (and frequent poster!) on this forum.  Gave her my references, and mentioned that I had some specific and kinda kinky preferences--- to which she agreed to and we set a time for 7 PM that night and she gave me directions to her place.  About 5 PM Andi Ryan returned my email to her that I had made previously earlier in the morning.  I turned Andi down-- being loyal to the provider I had already made the appointment with and knowing that if I canceled on her- -she might not be able to fill the gap and maybe lose some money.  I called the provider as I was leaving my house-- as she instructed, to let her know that I was on the way.  No answer. Maybe she's in the shower? I drive halfway across town, get to her door and knock-- no answer.  I call her again-- no answer.  Knock on door and then see a very pretty lady wearing a robe move behind the window blinds--but no answer.  I guess she changed her mind-- lady's perogative, but a call or notification that she didn't want to see me would have been nice!   It was frustrating.....
