Help Again? I know one of my contacts out there is real estate ...?

savvy. I filed chpt. 13 (Arkansas), in January of this year. Yesterday, I returned to my ranch to find an "notice to quit posession", from the company that financed my ranch, and of course I did include the ranch on my bankruptcy. It stated that when in default, they can call the notes due & payable, plus interest & penalties. How can they do this when I filed bankruptcy? and am I now destined to lose my only home?
