Hi, I have question to ask, I signed my lease for a certain amount, and I received a note saying that I owed money, when I went to go see what my note was about, they raised my rent and said they made a mistake on my original lease agreement, when I asked to see a copy of my lease agreement they drew a line over the original rent amount and put a new amount with the mangers initials. Can they do this, even though I signed my agreement with the original amount of rent?. help please :(
