The same thing of this thread
http://www.eccie.net/showthread.php?t=77211
happened to me. TWICE!!!
I made an appointment for Sunday. She stood me up. Around 1 1/2 hours later I talk to her and she is apologizes and tells me that she fell asleep. She promised to make it up to me if I reschedule for the next day at the same time.
Next, day, she does the same thing again.
I should have just not bothered to even think that she was serious about keeping her promises. Luckily I just called and didn't drive to her incall.
