question about child services?

i know this girl and she is 11 and she is adopted, and her adopted family is emotionally abusing and neglecting her. but she is moving into like a huge mansion, and so my question is, if i call child services, will they take one look at there house and go "well at least shes not on the street" or something like that and just like ignore it, especially because there isn't any physical abuse, well at least i don't think there is... also she they have another adopted daughter that they treat totally differently, she gets anything she wants,, and has better everything, cloths, bedroom furniture, gets paid for good grades, doesn't do any chores. while the 11 y.o. has to clean everything. i swear they use her as like a slave, and she get awful grades cuz no one will help her
