Help: questions about home modification program

I applied for home modification with Chase in May of this year and called them a few times over the last few months, but was told that they have not assigned anyone to work on my case. From the conversations, I sensed that they are working on people who are in the foreclosure process or behind in payments. I searched online discussion board and saw that people recommend stop payment to move ahead of the modification program. I have been current on my mortgage payment so far, but have tapped into my checking account\'s overdraft protection to pay mortgage for the last two months.

Should I stop paying Chase now to get their attention to work on my modification application? If I stop one or two payments, how bad will it affect my credit score? Will they start the foreclosure process on my home if I stop payments? What would happen next if I stop payment? Anyone have the same experience, please share. I welcome any ideas. Thank you.
