House Owner — hiding the matter of demolishing the building

I am not sure if this is the right place, but i am expecting an answer. I was sharing a room in a flat with a family. Two months before, the house owner told me that the building was about to be demolished and that it was quick notice. I thought that since this is the case, they might have received compensation money. But i came to know recently that they were not paying the rent for 6 months and they were taking rent from me all this time. They were in fact hiding a truth and cheating me. Where can i complain against this and is there any chance for me to succeed?
