Select Portfolio Services Has Frozen our ability to Sell Property Salt Lake City Utah

We have had a property that we have not lived in for 4 years.  Last year, we tried to sell the property and our mortgage servicer, SPS, refused to let us short sale it.  We had three offers and they were all declined.  Consequently, we requested a deed in lieu of foreclosure.  SPS informed us that we had a 279,000,000.00 lien on the property from Wells Fargo and a 179,000,000.00 lein from Wachovia and we could niether sell nor deed in lieu the home due to these liens.  We went to the court house twice and pulled the title of the home twice documenting that no such liens existed.  We talked to Wells Fargo (whcih now owns Wachovia) and they reported no debts were owed on the property.  We did title searches documenting that there were no leins on the property and over a period of six months we have relentlessly sent all this documentation to SPS requesting we be allowed to sell the property of deed in lieu it.  SPS has refused all these options and says we have to keep this vacant property. We are not sure of their motivations or why they would do this to us.  They have provided no documentation to us that these insanely large liens on a 200,000.00 property actually exist any place but in their minds.  Their is no way to pay off our debt as the imaginary leins are so massive that they are insurmountable and even if we paid off the house today they would not give us the title because of these non-existant leins they say are real but we can find no evidence actually exist.  So we are trapped with up keep of a vacant house we haven't used in 4 years.
