I live in a low-income apartment complex and when i moved in i was on maternity leave so i didnt have to pay rent. When i returned to work i reported it to our manager at the time and filled out paper work with her. I never recived a notice of change of rent. That manager got fired and now the new manager says i owe back rent for all those months. Am i responible for it even though i reported that i was working and the old manager didnt do her job?
