Theres a few particular staff that picks om my girl and kids, how can i report that and something actually be done about it?

Yup

I suggest that you put your concerns in writing. Submit a copy to each level of the administration (supervisor, manager, director). Tell them your concerns, that you would like to speak further with someone & in your letter, ask them how they plan on resolving the problem. By submitting it in writing & giving it to several people in administration, the chances are higher that your concerns will be investigated. Additionally, it will harder to slip thru the cracks if its in writing. Oh, give them a time frame of when you would like to hear back from them. And don't forget to keep a copy for your records
