As for posting a negative review, they aren't going to allow it on this website unless a meeting took place.  If you never met her, then they won't allow that negative review.  

Best not to dwell on this too much, as you will never know what her problem was anyway.  If she emails you later to apologize, then maybe you might forgive her and try again.  I would say that unless that happens, forget her and find somebody else to meet with and just move on.  There are too many fish in the sea to be dwelling on women like this.  

By the way, this happens to everybody sooner or later.  Once a provider does that to me, I will never rebook with her, even if I have seen her before.  Unless she contacts me to apologize, which is forgivable.  

But when a provider no call/no show's me, that is completely disrespectful.  I will not see providers who act like their time is more valuable than everybody else's.  Take my advice and adopt the same principles for yourself, it will result in you wasting less time and ending up with better women over the long term.  Like I say, there are thousands of fish in the sea anyway.

As for why she did it...one of the more common reasons is that a "regular" contacted her after she agreed to see you and he wanted to see her for a longer date.  And you got bumped.  It's also likely it happened again the second time as well.

You could post an inquiry on your regional board asking about her...but beware that as a newbie your credibility will be questioned and her WK (white knights) contingent will roast you in all probability.  But you might also hear that others have had similar issues with her.  Gals that do this are fairly well known in most regions.

The better option is to PM a few of the recent reviewers and ask them if they have heard of this behavior.  That way you won't highlight your irritation with the situation and maybe find out that she does this routinely.

In any case there are plenty of other gals that will be quite happy to accept your money.  Don't let one gal who is "not professional" to sour you on this game we all play.

You may hear from her at some point with an exotic story of tragedy.  I wouldn't waste another second on her...as all that has happened is her cash ran short and you might still be a willing dude.  I'd hate to see you become a three time loser.
