Far as title - it has to transfer or the house still belongs to you. You can wait for them to foreclose, or you could sell the house ( or short sell if that is the case)
I hope I am reading your question correctly. Perhaps WAMU charged off your mortgage because it was included in the BK. This would also be the reason that they cannot call you back. If a BK is coded, the lender certainly does not want to contact you by phone.
Why not pull your credit report and see how the mortgage is listed there. It should say, charge off included in the bk.
If the house is still in your name it might be because the lender has not foreclosed yet. Sometimes the lender takes over 1 year to foreclose and take back title.
I believe you have two questions. the bk is the first question. The second question is the title of the property.

If you need help reading your credit report, I can assist you if you would like.
You can call a local Title Company to see who is on title for the property. Good luck!
