A Chicago-area utility is warning customers about scam artists posing as employees.
Commonwealth Edison said yesterday it has seen an increase in scam reports.
The utility says con artists have been contacting small businesses and other customers by phone and in person. They claim to be ComEd representatives seeking payment.
Sometimes the impostors claim a customer's billing cycle has changed and an immediate payment is required. They have instructed people to buy a prepaid credit card and to call back with a personal identification number.
