Sorry about what happen, I am only guessing you are new at this and no doubt this will happen a lot more over the coming years, so get use to it. Its part of the territory .
I personally have know and seen this provider many times over the last 5-6 years and she is a responsible person . I am sure there were personal things she was dealing with that is none of our business nor does she have to discuss them with anyone in this underworld lifestyle we indulge in .
I last saw the person you mentioned one week ago and it was to be a Double with her friend, Her friend shown up very late and we started without her friend and she was AZMAZING that I was glad it was a one-on-one session, as she was GREAT. It looks like she may not afford you that opportunity to experience the same thing, based on your post. But hey, what's that saying.............."There lots of other fish in the sea, so no worries".
I have been in your shoes many many times before and it was not until it happened a few days before Christmas some years ago that I learned to turn a horny moment from a cancelled meeting at the last minute to a positive event when I went to a close-by mall and shopped for MYSELF with the donation & gratuity fees I had in an envelope . I had a great lunch to boot and it was the gifts that kept on giving back long after the 60 minute I had allotted for a special meeting that never happen because she did not pick up her phone after I got to the hotel .
I have never done what you did and posted my frustrations to the board and called someone out, hopefully ladies doing their research for future meeting with you , will be understanding of your post.
For me, I am very grateful and appreciative for the opportunity to fulfill a fantasy and just like a relationship , sometimes things don't work out. Let it go and me mindful you can afford to do this later again some other day if you don't go out to buy a new set of golf clubs like I did
