I'm so irritated

Courtney
Monday night when I came home from work I noticed part of my roof in my laundry room had fallen in and was leaking water. Tuesday I called the apartment office and after calling them 3 times thy finally sent some one out a schedule they said they'd come back but never did Wednesday I again called and called finally 6:30 at night they sent some one out and the fixed the leak that was from the upstairs unit and cut out the fallen drywall and taped up a plastic bag and said well be back Friday. Today I walk out there and the bag had fallen and u can see mold. Really how is this safe... I don't know what to do I'm getting married in 3 weeks so it's not like I can up and move...
