Bathroom ceiling leaked for 6 weeks before they fixed it. Mold confirmed after.

Noticed a water stain on my bathroom ceiling in February. Submitted a maintenance request February 9th. Multiple follow-ups. They came March 15th, five weeks later, and patched the drywall. April: the stain came back. Had a contractor friend look at it. Mold behind the patch, likely been there since at least January. Now I'm fighting with management about whether the unit is habitable.
