It sounds like you've talked to the right people but simply haven't liked the answers they've given... I don't know that anyone here will be able to offer better advice.
You should be able to condirm if the foreclosure sale happened or not through court records or maybe in your area the county may update a data base on the internet. If the foreclosure sale has been completed I would try contacting the REO department at Country Wide. This would be a different department and would not be tied to the people working the short sale.
If the property has not gone to sale get the mortgagor call to get status or send a president letter to Country Wide to get a status on their loan. You are not the banks customer, the mortgagor is and they will answer questions by the mortgagor and not you. If the mortgagor call the foreclosure attorney the attorney should tell them a status as well.
