Lack of ABC channels on TV due to SCripps contract.

When will we here in Michigan once again be able to view shows on ABC.  It is very frustrating that I pay a lot of money every month for my contract with Comcast, yet i loose a major network and am unable to watch some of my favorite shows.  Can you give us an idea when this will change, or do I have to find another provider for services?  Will we be given a credit for the days/ weeks that we go without ABC programmiing?
