Relentless woman trying to save me money on my energy bill. I told her a couple times I wasn't interested and finally had to hang up. She called back right away so I blocked the number.

very rude "lady" calling about Nicor Customer something-or-another. ask a lot of questions, and don't let her answer them. she gets angry and leaves you alone

Asked for the owner and wanted to talk about a rebate for Com Ed. Wanted owner to contact her at a different number 800-210-9011 ext. 1598, said her name was Wendy Sabrino, and to have Com Ed Bill in hand.

Voicemail claiming to be from a gas company asking me to call back with "bill in hand." Don't ever give them an account number. They can use it to switch your service without your consent, claiming that you gave it to them for that reason.

American Power & Gas - wanted to find out how much I was paying for electric and gas to see if they could do better.  At this time my rates were better than theirs.  The guy I spoke to was very pleasant.
