Lost some of my local channels

I live in Richmond, Indiana which is literally right on the Ohio/Indiana border.  Because of this fact, up until a few days ago, I was getting local channels out of both Dayton, Ohio and Indianapolis, Indiana. I actually physically live closer to Dayton than I do to Indianapolis. When I called customer service, I was told due to a change in the Nielson markets, I'd no longer be getting the Dayton channels. I need both sets of channels. Living in Indiana, I need the Indianapolis news to know what's happening here. But living so close to Dayton, I also need their news since I work in Ohio and am more affected by Dayton's weather than I am Indianapolis'. How can I get those stations back?
