Who do I notify for these problems?

My daughter is having problems that I myself have seen in her school. There are four faculty members, to start off with, that are either not doing their job or are having reacurring problems. The new math/science/seventh grade homeroom teacher is unorganized, unsanitary, and just isn't able to teach the students period (she even blew off a meeting with another parent at lunch time so she could eat). The gym teacher is a grumpy man who yells at students without reason...he's not a gym teacher thats mean because he's tough, but he's just plain rude. There is a "Lunch Mom" (people hired to help out with lunch) who I myself and my daughter along with many of her friends, have seen numerous times leaving the bathroom without washing her hands, and she is also quite rude to many of the students. For the final faculty problem, is the principle. This lady is utterly ridiculous. She yells at the students for things they have not done, has been known to use profanity to and in front of students, and ignores her responsibilities as principle. Other problems in the school include the floors in the gym, in which the students have to lay down on for excersises, not being clean even though the cleaning supplies is there for it, tiles from the ceiling and the floor being taken off or falling apart and not being fixed, and cracks in the floors and the walls. This is a private school which I suspect should be able to hold up better than most schools, but by my descriptions above, is not. With what I'm paying for this school, I expect a fine education and place period. Are these usual problems had at elementry schools? I have gone sometimes and told the Diocease of Joliet about these problems, but nothing has really happened. In fact, all that's happened is that the Diocease will call the principle, who then later talks to me and asks that I not call them anymore. Obviously, I am not planning on listening to this woman anymore, so I would like to know where else I could take this information and have something actually done about it. So, where else, besides the Diocease, could I go????? Help?
