HELP to Short Sale Buyer- Selling is Rent Skimming

[Jen Kapela]

I am really hoping that the professional real estate experts (or even just really smart people) in this forum can help me!!
I have been trying to purchase a short sale property in Colorado for almost 10 months now and I have been renting the property from the owner this entire time- over $14,000 has been paid to the property owner while we have been waiting for this short sale to be approved.
A very long story short, it is now apparent to us that the home owner has not submitted our short sale offer because he has enjoyed collecting our rent every month. He is now giving us 2 weeks notice to get out so he can try to short sale the property again and avoid a foreclosure. We have refused to do another short sale with this sleezy guy, just hoping to purchase the property at the foreclosure auction, but the bank keeps extending the sale date and we cannot figure out why?? The home owner has not paid on his mortgage in nearly 2 years!!! but the bank still does not foreclose on him. This guy really knows how to play the system and it is obviously working for him.
We have maintained the property like our own, made repairs, kept it up very well, love our neighbors and have 3 kids in the local school. We do not want to lose this house, but it is no longer possible to work with the home owner to purchase the home. The property is scheduled to go to auction on May 11th, but we need to be moved out of the property by April 30th.
I have tried SOOO hard to get in touch with ANYONE at Metlife who will listen to my story, and look in to this guys situation and care at all about the rent skimming or other fraudulent tactics this guy is doing.
I would love any advice on how to get someone from Metlife to FINALLY send this home to the foreclosure sale or at the very least, how do I get in touch with someone at Metlife and have my situation heard?
Thanks
