my mother's nursing home can't make her move out because they say we complain too much.

More info: 

Illinois allows a nursing home to discharge a resident for not paying the monthly fee, or consistently paying late. The home can also discharge a resident whose behavior is dangerous to the resident or other people. It can discharge a resident who needs more care than the staff can provide, unless the resident doesn't want that kind of care and staying does not endanger other people. For example, if she needs surgery, she may need to go to a hospital, but if she refuses the surgery, she should be able to stay. A nursing home may never discharge a resident because she or her family complains about the nursing home to the staff or to anybody else.
