I had seen some pretty steady reviews for the girls from the agency, nothing great, nothing horrible but pics on the ads seemed to be getting better and better so I eventually booked an appointment.  I sent and email and a text specifying the provider name I wanted to see and after the appointment was confirmed I sent another text right before I arrived confirming I was on time and specified the provider name again.  
When I went in the girl did not appear to be the same so I just figured that the airbrushing must have been a little out of control.  After my session I saw another ad for another girl and the pics matched the girl that I saw for my appointment.  I sent numerous texts and emails to agency trying to confirm if that is their usual approach - fill the appt with whichever girl is available - or if you can confirm who you want to see.  None of my messages were answered so they are clearly ducking the question.  I tried to sort out with them directly before coming here but since they don't want to own up to it I figured people should know.
