I agree, I think they truly don't exist. They are just fake names added to the roster list promising extra services at cheap prices in order to try and entice us to visit, then when you show up you are told they are busy/not working and you have to see one of the other girls. This has happened to me 4 times already at different times of the day. I ask for KaKa or MoMo and almost always get greeted by or directed to Lisa, who just seems to be the Viet girl on rotation at the moment, living at the spa, working 24/7 until her visitor visa runs out and she has to go back to Vietnam, and they just bring in another girl on a visitor visa again.
