Does anyone know how to reach the Wells Fargo investors?

I’m working a Short Sale with BoA as the processor, I just found out that the note holder - a division of Wells Fargo (investor) does not negotiate Short Sales and the short sale was canceled? It’s a conventional Jumbo loan ($750K) and the property needs about 350K in repairs. Also, the property owner just filed chapter 13 so this property can be tied up for a long time. I’m hoping that if I can get this info in front of the Wells Fargo investors they may reconsider since they stand to lose lots of money if they don’t re-open this Short Sale.

Thanks
