To me, that seems like a really high frequency of ghosting, but I think you're hitting up the independents and I'm hitting a few regular agencies. I think the dynamics work a bit different in the two settings.

 
Obviously it's something no one wants to experience, and providers that do so often should be avoided. But, I think ultimately it's a case of just putting such providers on a do not see list for yourself (or maybe someone will put a site up where honored appointments and ghosted/cancelled appointments could be tracked) and move on. The post might help for a week or so but so many other paths to the ads/providers for people who never saw you post or never saw TER that someone will likely always be ringing the bell on her door.  

 
So the big question, have you at least made a session with someone else so you can forget all about Mia? Like the old saying goes, the best revenge is living well. Hope you had an awesome session with some other girl.

I don’t do deposits for reasons including this type.  
I have had this done to me 6 times. She, and/or her booker was not only out my donation, but if any of you guys decided to avoid her after reading my posting, she was out another client.
OBTW, Daisy is still advertising. I had hoped she would have lost enough business so that she would move on. I hate when people don’t show.
