I finally answered this call.  This pesty number is from the IL Dept of Revenue.  It's just a recording so don't be afraiid to answer.  It's best to clear that matter up quickly even if you owe money & can't afford to pay.  If you can't afford to pay, make a deal with them.  If you at least explain your situation, a lot of times the amount can be reduced.  However, it will never go away so be brave & deal with it.
