Nationstar Mortgage Denial of HAMP mortgage, offered other alternatives, then told they are not available to me ,Internet

I have been trying to restructure my mortgage with Nationstar Mtg since 2/11/11.  First they needed more information, I submitted it, even though it had already been submitted.  Then I was denied because they stated I didn't live at the property, I had to provide documentation that the town renumbered my street.  Then they had everything they needed and sent it to the underwriters.  After 92 days I received another denial because my current monthly housing expense is less than 31% of my gross income.  This calculation should have taken them 5 minutes when they received my paperwork in Feb.  They gave me the run-around for weeks to only deny me.  When I received my denial letter, I was given an alternative of the Payment Reduction Plan and when I inquired about it, they said they did not offer it.  Then why was it on my letter.  I was offered to refinance.  I was given the options of a 20, 25 or 30 yr mtg.  Was told I definitely qualified for each.  After careful consideration I went with the 20 yr and received an e-mail back stating I did not qualify.  This company has given me nothing but the run-around and I feel they use very shady practices.  Every time I speak to a person they have different information and are very misleading.  First I'm told I qualify, then I'm told I don't.  I am only trying to keep my home and they are not offering any solutions.
