WHO DO I FILE A COMPLAINT WITH MY APT. COMPLEX HAS BEEN TELLING ME THAT THEY R GOING TO REDO MY TUB FOR 3 MOS.?

i MOVED IN OM THE 1ST OF APRIL AND THE AC UNIT IN MT BATHROOM WAS LEAKING OVER MY TUB. IT TOOK THEM A MONTH TO FIX THAT. FROM ALL THAT WATER LEAKING MY PAINT IN THE TUB IS BADLY PEELING TO THE POINT I CAN NOT TAKE A BATH I HAVE TO SHOWER EVERYDAY. I CAN BARELY CLEAN IT WITHOUT IT COMING OFF. THEY HAVE BEEN TELLING ME THAT THEY WILL REDO THE TUB SINCE THE END OF APRIL. AND THEY WILL NOT GET ME THE OWNERS INFO. THEY CLAIM THAT THE APARTMENTS HAVE BEEN BOUGHT OUT AND THEY DO NOT KNOW THE INFO. WHAT DO I DO? FILE WITH BBB OR WHAT?
