How do I review a provider whom does not show up? We made arrangments and she was not there when I arrived. Do I give an "Overal Performance" of a "1=Total Rip-off"?

I don't believe no-show reviews are allowed since there was no meeting to begin with. On the local board in my region, when there is a no-show a single post stating that a particular girl didn't show up for a scheduled date is allowed. Contact your moderator.
