Said they were with Comed. Needed to speak with responsible party. I said I do not have Comed!  They said they needed to speak with me about my Nicor acct.   I told him I do not use Nicor and to never call again!  Such a scammer!

Told me it was about my Nicor gas bill. I hung up on them. Usually don't answer, but called my cell and that doesn't say who is calling unless it is a number I have saved in my address book. Number does NOT belong to Nicor, probably not even to any legitimate company. Most likely a total scam.

called at lunch time---didn't leave message
