"The best way to combat scams is to understand the tactics criminals use to trick customers into giving up personal information," said Maria Gomez, security supervisor for Ameren. "Scammers have become more sophisticated by masking phone numbers to appear that the call is from Ameren or by calling residential or business customers during busy times of the day in an effort to confuse their victims. Customers can protect themselves by looking for and recognizing the scam schemes and reporting them to the appropriate authorities."

"Unfortunately, we're seeing an increase in scam attempts as these criminals prey on our customers during this period of uncertainty and heightened anxiety," said Mary Heger, Senior Vice President, Customer Experience, Ameren Illinois. "They're deploying more aggressive tactics, like asking our customers to download payment apps like Cash App or Zelle while keeping the customer on the phone. We're asking all of our customers to be on high alert."
