Mold In my apartment what do I do

So I will try to make this as short as possible but I live in subsidized housing with my two children. Since my second son was born into this apartment he has had rsv, croupe, random hives and is ALWAYS sick and was diagnosed with asthma. Now i never thought of all the flooding we had in our basement having anything to do with it. We lost several items in our basement due to mold. Now I’ve noticed black mold in our bathroom on tub, tried bleaching it comes back. And it’s all around my windows. We’ve had maintenance come spray the mold, we’ve had them suck out our basement of the several inches of water anytime it rains, they have people come out and “fix the leak problem” nothing gets fixed. Finally saw my sons new allergist that we were referred to and he tells us all this mold is causing my sons issues including the hives on the skin etc! I’m so livid. What can I do??? Are they required to have me moved immediately ? Do I call health department? I can’t believe my babies been so sick for two years of his life due to this crap. Anyone who can help with what I should do comment down below
