A heads up on a potential scam being used against Ameren business customers.  Company officials say they have been made aware of at least ten attempts recently of someone posing as an Ameren official asking for the customer to make a payment or face losing their service.

Ameren Spokesman Brian Bretsch says con-men are calling businesses and telling them their lights are about to be shut off unless they go buy a pre-paid Green Dot card and pay up.

Bretsch reminds customers Ameren reps will never call you asking for immediate payment over the phone.  If your bill is delinquent, they'll send out a notice in the mail.  He says Ameren employees will work with you to work out a payment plan.
