My ceiling collapsed. My super did nothing, what should I do?

Dec 9th I noticed a small wet spot on my bathroom ceiling, and I told the super. He looked at it and said "I dont know what to do, just call me if it gets worse."

On the 14th It got worse and I called him again. Same thing, he looked at it and did nothing.

Last night the ceiling collapsed and the bathroom is a total mess. What should I do? I would really like to fuck over the owners/super if possible because they are terrible, but I also want to move out of here. Can I just not pay rent and move out?
