The system is very messed up... I'm so sorry. You're doing the right thing though. Keep it up and eventually someone will listen.
We had a family in the neighborhood with kids that were bring neglected. CPS took the daughter away but left the boy with the parents for another year and a half. They finally got sick of hearing from me and eventually removed the boy too. He contacted me on Facebook not too long ago (he's now 22) thanking me for looking out for him. He's doing well, will be graduating from college this year!
My thoughts are with you.
