CW is tough, but the listing agent has to get in touch with the foreclosure dept. and find out the person handling this loan (now in default.) and get an extenion on the foreclosure date if ione was given. Then he must get in touch with the loss metigation dept and find the negoiator for the transaction. They will need to document ALL names of who they talk to with their phone numbers. It will take multiple phone calls to get to the right people. They have to be persistent meaning multiple calls EVERYDAY. Then they will have to do the same with the second lien holder, to negoiate their payoff. If the listing agent is not experienced in pre-foreclosure or short sales, get their broker involved. 7 weeks is a long time, but not uncommon. If the agents aren't contacting the right people, it can simply get lost and forgotten. They must be persistent to the point of being annoying.
If you really like this property, hang in there. It will take a while. If not, withdraw the offer and move on.
I hope this helps. Good Luck
