Where do I make complaints about my apartment complex?

I live in Ohio and my neighbor in my building burned his apt. to a crisp in a grease fire causing my apt. smoke damage and burned the wall around my door. the carpet near the door is also ruined. the apt. complex sais my insurance should pay for this but my insurance is only taking care of my personal items in the apt. not the apt itself. where can i make a complaint in the state of Ohio?
