why wouldn't there be any visiting schedule times set up for someone in clark

county detention center NV? To visit an inmate in clark county detention center in las vegas nevada, you now have to register with the center and then set up the visits through the computer. Well Ive been doing this just fine, until the other day I tried to schedule a visit with my boyfriend like i do every sunday, and i had noticed he had been switched to a different housing unit. when i try to set a visit up it says "No personal time blocks setup for inmate's housing." and when i call it is always busy. can anyone please tell me why this would be happening and why can i not visit?? whats the deal? thank you
