I applied to an apartment at the very beginning of December. They didn't call or email me for months and they didn't cash the $90 check I gave them for the application fee. I recently moved in to another apartment because the first one wouldn't answer my calls. A few days ago I cancelled the $90 check because I STILL hadn't heard from the first apartment. They called me today, saying they could sue me if I didn't bring them another check or money order. Do they have a right to do this?
