I once had an agency cancel my redez-vous because the girl did not show up for work.
They then offered me a girl new to the business that was not listed on their site.
It was only 2 weeks later that she finallly showed up on their roster working on 2 occasions and then leaving the business.
I never wrote a review as she never stayed long enough in the business.
I always wondered if agencies keep SPs new to the business for select and regular clients before enabling them to be booked by everyone else?
