Looking for SFA Talent agency.?

SFA Talent from Universal City Ca. stole over $14K from my son who did a commercial for Toyota while with SFA and they never paid him, I found out how much his earnings were when I received his W2. I since filed a Labor Board case against them but can't find them at their prior address in Universal city. I was with the L.A. commissioner and they have advised me that I have to serve them with the court papers before the case can go on, does anyone know anything about them? please help!
