Thank you for this story and the good news. I have some old friends and former co-workers who were actually tapped to come out of retirement and work on resolving some part of that nightmare mess in Michigan. I didn't find anything on AZ having done this, but suspect that they have contracted out their overpayments to some private firm from the sound of this person's situation. I agree, the OP should just make sure they aren't due any state or federal income tax refunds back while this is hanging over their head.
