Ajnat,
I'm sorry you are dealing with this in your life! This situation is horrible.
Children need adults to be their voice when they are in bad situatiuons. They are too young to be able to take care of themselves and therefore are stuck in bad situations like this one.
If you do nothing else but try and find away to help those children do that!! No child deserves to have to live in that environment! I would most certainly report them!
