Wisconsin Public Service (WPS) is strongly urging businesses and residents to be mindful of a sharp surge in scam phone calls. In the past 24 hours, more than 100 phone scam attempts have been made by people impersonating WPS employees in order to fraudulently obtain money. WPS strongly emphasizes that its employees never require customers to pay utility bills with prepaid cards. WPS also will not solicit payment from a customer in a threatening manner. Customers are reminded to never provide any banking, account or private information if they receive a suspicious call.
