The apartment above me flooded causing my apartment to have a major leak a few days ago and there was water pouring out the ceiling vents in both bathrooms, the smoke detector, and light fixtures. They knocked out our ceilings and within less than 24 hours new drywall was installed. They did not check to see if any electrical systems to see if it was affected (my kitchen is right next to the bathroom on the same wall), the carpets were soaking wet, among other things. They are beyond slow on the repairs and continue to use MY personal belongings to vacuum drywall and clean the mess made.

I want to either get this fixed correctly and quickly or cancel my lease. How should I proceed?
