Caller asked for my husband by his nickname and that he was calling about our Duke Energy bill. I told him that he was a scam call and to not call again and I hung up. He called again and tried to tell me he wasn't a scam caller to which I replied that he most definitely was as first he asked for my husband by his non-legal name and if he called again, I would find a way to bring charges against him/his company.
Any of these calls that claim to be about your utility bill are pure scams. ComEd and others will notify you in writing. Keep an air horn by the phone for these crooks.
