I'm in a similar boat.
I did not front her money... but I have deleted her contact (after trying so hard to get it) to reduce the temptation of attempting to schedule ever again.
After months of trying to get ahold of her I managed to get a response through email and grab her new number. We set a time and agreed on 2 hours.
With much effort on my part I was in the room about 30 minutes after scheduled time. I even offered her an extra $50 if she got me in there within 10 minutes of schedule and she couldn't make it happen.
Once inside, she still looks great and has the service-minded attitude but it was interruption after interruption the entire time. Fear of being kicked out of the room, no ID to renew or get new room, dudes coming to the door to get cash/food, phone calls and texts, etc....
I was so disappointed and unable to really get in a groove with her that I actually called the session early. That's right... after making it into the room with THE FREAK, I chose to leave early.
Gave the reduced donation, showered and left.
She did not complain about the reduced donation.
