Landlord said in a text i was the only tenant that complains. I had an inspection and it passed landlord was there during inspection and told inspector it wasnt mold and inspector believed him soon after . I started communicating with landlord telling him that water was leaking from roof he sometimes would not answer his phone or he would rush me off wall blaming buildmanage but he wouldtell property manage not to come do work or do patch work.
