I think you are way beyond the need for a QWR. You need to start a lawsuit. They have wrongfully foreclosed. They did not have standing and you probably signed your name to a predatory loan. You need to read up, go to livinglies dot wordpress dot com to see if there is any help in your state with attorneys who get this fraud thing. Not many do, or they are not willing to fight the banksters.
Good luck, I think we all need it.
