They signed up December 12,2011 for a plan that has 6 months for free. So that means in June of 2012, they'll get renewed for $215. At that point, the renewal will last until June of 2013. And since that renewal hasn't happened yet, they're only active until June of 2012. It seems like that screen is showing what I would have guessed it would show.
Have I misunderstood something? I don't think it should say that it expires in June of 2013 because that renewal in 6 months may fail. Once it gets renewed though, then it should show the date you're expecting.
