Renting a house in foreclosure?

I was recently made aware, through a certified letter from the Bank that holds the mortgage, that the house I lease is in foreclosure. The Bank says to send payments to them. I did this month, and the Propety Manager called a week later and said that I was past due on my rent. I told him about the letter from the Bank, and that the letter gave the appearance that he was no longer affiliated with the property. He said to continue to send payments to him until which time the house was foreclosed on, which would terminate my lease, or his firm was terminated by the owner or by the pending foreclosure. In the meantime, a for sale sign appears in my front yard, and a realtor was in my house showing it to a potential buyer without my knowledge while I was away on vacation (I came home to find his business card on my table) AND they re-arranged my landscaping to take pictures to post on their website (the landscaping was put back, but I saw the pictures of the house on the realtors website showing that they had moved everything around). I am caught in the middle of a big mess. My question is this...when the bank forecloses (and I was told on the phone that they could not tell me whether the house was in foreclosure at this time, but could in 2 weeks), is my lease null as it is with a Property Management company and not the bank or the owner of the house directly? If the past 3 weeks are an example of what I can expect, I want out.
