1) If she lost your number (i.e. broken answer machine, non working voice mail, etc), she has no way of calling you back. It's possible.  You did not mention if she has an answering machine or voicemail.

2) If she got it and has been slow to respond. She's not very professional in her attitude. I would move on.

She could be like me, a fluffy ball of jetlagged undercaffed and non secreataried piece of action.

It really boils down to whether or not you want to suffer an idiot or not.

All the regular excuses aside (lost number, broken machine, etc) if she was really interested in seeing you and was sincere in her protestations that life had caught up with her and she had to cancel, she could have found some way  to do the right thing in 5 days time.

If you really want to see her, great, do so.  Just remember she is a flake and as such, tends to the behavior of an idiot.

If you aren't into suffering an idiot, move on.  Plenty of great providers out there with their heads screwed on tightly that have great bodies, wonderful attitudes and spectacular moves.

Just my opinion and I could be wrong.

I'd say what you want to do is based on how hot you think the lady is.

If you read the Vegas board, there are several girls who flake out on their clients, are habitually late (like 2-4 hours); cancel, reschedule and cancel again, or just plain no show......yet if they are "hot" enough, the guys rave about them and say the effort and wasted time is worth it. Sometimes I can't believe what I'm reading.

Raving about the lady and excusing her bad behavior just reinforces further bad habits.

Being cynical, it seems to me that men will forgive a lady almost anything if she is a hottie.

YOU (provider) get one chance to make a great impression. Like a resturant, how likely are you to return for a meal when its been botched. Apologies aside, there is no reason to return. The seas are filled with tuna, shark, and 'cuda... why waste your time on some frumpy, spoiled, and inconsiderate lowlife?
