I'm not a lawyer but I do read a lot of legal books and case studies. First off you should seek legal advice.
That said....I'm afraid it was up to you to read the rules BEFORE you rented. I don't think you have any recourse in this matter. if the people in charge are rotten and really want you out....i'm afraid they can kick you out....and your only recourse would be an expensive lawsuit which in my opinion you would lose.
sorry to be the 'bad' messenger.
