There are lots of issues with how banks are processing foreclosures and how things are coordinating the process. It may be difficult to get someone at bank to listen to you but neither chase or any other bank is using inappropriate foreclosure methods. The law lays out what is required to foreclose and the banks hire attorney's to follow those processes.

My advice, do whats best for you. If you cant make your payments, just work a cash for keys program, tell them you want $5000 to move for expenses if you end up in foreclosure.
Good luck with everything.
