Everytime there is a maintnence problem they come on thier time & when ther isnt a maintence problem there is a sewage problem! My mother in laws sink didnt work 2 weeks ago & im on the lease as well & NOW the sewage is backed up & its her only bathroom I hope they dont make her wait 3 days with a bathroom or there will be a problem.
