A man with a very heavy foreign accent (sounded like he said "Mark") stated he was calling about my NICOR gas bill, asked if I was the responsible party on the NICOR bill. I told him I do not have a NICOR gas bill, so he said he was calling about my ComEd bill. I promptly hung up.
I think it may also have been "energy supplier", but "John's" accent was so heavy I could barely understand him. He wants to know if you are responsible for your Nicor gas bill. I told him yes, so then he tried to proceed with a sales pitch about switching (to what I don't know), but that you would still be billed through Nicor. Again, the accent is so heavy you have no idea what he's trying to pitch. I did asked to be put on their do not call list, but I enjoyed my brief 2 minutes of entertainment from "John"
