Current Rehab Facility will not release my dad even though we have another place for him to be at to get better care. What can I do?

My father has been in rehab in horrible conditions and the facility is treating him poorly. I have been calling them non-stop to find out details, and the social worker gives me attitude every time I speak with her. I have complained to the state, but I need to know if there is anything I can do to get my father out of there immediately and into his new facility. He is rapidly declining and I fear he won't recover. I have spoken to the local ombudsman, but is there someone else I can call?
