ATTENTION: Once again Willmar area businesses are getting calls stating that their electric bill is past due and that they have to pay immediately in order to avoid a disconnect. THIS IS A SCAM! It is not the practice of Willmar Municipal Utilities to call customers and demand payment. Should you receive a call of this nature please contact the Willmar Police Dept. And please refrain from making any payments to the caller before checking directly with Willmar Municipal Utilities.
