This caller continues to call stating they are Nicor gas and need my account number to issue a credit. I always hang up the phone. I called Nicor and verified this is not them. It is some other independent supplier who is trying to switch the gas service, that is why they need the account # - by giving that to them you give them the right to switch services. Nicor stated they will never call you and ask for your account number so BE WARE!
Caller: Nicor Gas? Not!
