Landlords in NC are not obligated to provide, repair or replace A/C units. Your luck ran out. If you want the mold cleaned, you will have to do it yourself. That's your obligation. What's a "hold in the ceiling"? They are not required to patch it, texture it, repaint it, and make it pretty. If it no longer leaks, then they did the job required of them. If you reported them, assume they forgot. Report them again and ask them when they might get around to fumigating the place. When you pester them about things they are NOT required to do, it becomes harassment and the thing or things they ARE required to go, get lost in the shuffle - are considered harassment. Don't mention anything else. Concentrate on the water bugs.
