GMAC Financing/Maradith Moonshew Please help me figure out how to get results! Waterloo Iowa

My life has been h*ll for the past 10 months!!! I have a house I bought in Las Vegas Nevada and it is on its way to foreclosure unless I can get help before the dead line of March 4!!! I have been waiting for a short sale for 10 months, I have currently stopped making payments because I can't afford it for about 5 months. The house has 2 loans which the bigger loan is through Wilshire and the smaller is through GMAC. Due to my begging with Wilshire I have gotten them to approve me for a short sale which needs to be processed before March 5. I have been trying to get a hold of GMAC by letters, phone calls and agents, but there is no response from them. They are ignoring everyone even Wilshire who is trying to negotiate a deal with them. If GMAC does not negotiate on the short sale before the date then the Wilshire short sale approval cancels too! This means my house will be in foreclosure!!! I have a pre approved buyer which means that GMAC should consider looking at my application, they loose more money through a foreclosure! I can't understand what kind of company curropt company I am dealing with! I don't know what to do!!! Is there anyone that can help me?
