Appartment flooding

Location: Texas

2 weeks ago I had a minor leak in my apt from my upstairs neighbor, the said they found and fixed the problem. Well 2 days ago water started pouring out of my ceiling in my bathroom, multiple vents, my hallway closet, and through the baseboards in my bedroom closet, multiple water pockets in the ceiling and 2 of my door frames had cracked and were dripping water. There was at least an inch of water on the bathroom of the floor, maintenance came again and again said they found and fixed the problem. When I asked the apartment manager she said there was no chance of it happening again nor will mold grow and that she would hire someone to fix the damages and it would only take 2 days to fix the entire issue. even tho I expressed my concern about how water was in the actual walls and ceiling and that I didn’t feel comfortable living there and risk getting sick the only option she gave me was to give a 60 day notice and move out in 2 months to avoid a cancelation fee and if I wanted to leave any sooner it would cost me more money as well as effect my credit. Is there any legal route I can take to be able to leave sooner and not have to pay any extra fees?
