Yet ANOTHER alleged ComEd switcheroo company.  This time it's a male voice "informing" me that I can reduce my electric bill.  Here are two other numbers in case you get calls from the female robo voice:
312-376-8388
773-273-8487

Thank goodness they call my office number, otherwise my phone blocker at home would be full by now!!!!!
