I'm sorry to hear that! There was certainly chemistry between the two of you, but I think he was playing games from the beginning. Almost all the time someone says he fell asleep is nothing but an easy way out.
Believe me... the only surprising thing about this is the fact that you've already met him, don't get misbehaviors like this too personal they happen on a monthly basis and please don't write "only right now, no advanced appointment", be flexible. Some folks call at the moment while others schedule days ahead and unlike this guy keep their word.
Never count your chickens before they hatch, if you have time to meet another client before someone who already booked you just do it.
