A pipe burst in my ceiling at some point while I was at work. Maintenance was notified by my neighbor at 5:20pm,he was called back at 5:50pm and informed maintenance was on the way. It is now 12:20AM and maintenance has YET to show up. My apartment is super flooded, the ceiling is still POURING water. The parking lot is filled with water now, too because my apartment is so saturated that the water is going through the building. I need the water turned off immediately.
