Mr. Cooper review: refusing to review short sale and would rather foreclose

I have been trying to short sale my property ever since I was denied for a loan modification. I feel I am being discriminated against and the lender has refused to review very good offers with my short sale submission. Most recently I turned in a complete package and Nationstar refused to review and delayed for 2 weeks. Finally they opened the short sale package, only to tell me two days later that there is not enough time to approve my short sale, they are refusing to review my package and will proceed with the foreclosure. Janine Richardson with the bankruptcy department told me that my package should have preceded as my bankruptcy was dismissed the middle of December 2013, that the short sale department should not have delayed as they had proof of the dismissal. Please help, Nationstar is determined to foreclose on me when I am trying to do the right thing.
