OCWEN Cannot get a straight answer and they are sending strange men to our home to harass us. Internet

Our loan was sold to OCWEN and was transfered on 3/12/2013. We were in the middle of a loan modification with Homewardbound and were told OCWEN would complete the process with us. Last week, 3/24/2013, we were told that Ocwen sold our house and we had 30 days to get out by a man who came to our house representing OCWEN. We did not recieve a 30 day notice of intent to sale, nor was the property ever listed for public auction or sale. The county in which we live has no record of our property being sold or foreclosed on. Then we recieved a letter saying that we still qualify for a modification but when I tried to fill out the paper work again they said I cannot because the house is REO. When I call this place every time I get a different answer.
