Danielle, I am so sorry to hear what has happened to you.
I do think you need legal advice..........if I understand you correctly, you paid the rent, but the management company that collected it never paid the landlord, and "ran off" with your, and other people's, money?
If you have proof you paid, I can't see how the landlord can force you out.
It seems to me he needs to go after the rental office personnel, and as long as you continue to pay your rent on time, I can't understand why he'd want you to move.
If I am missing something here, please fill me in.
If I have it correctly, and the landlord continues to harrass you, please seek a legal opinion for your own protection.
Hope your ankles heal quickly!
