EnWin Utilities has issued a warning after some of their customers have received “threatening phone calls” to pay their hydro bills.

EnWin officials say customers have been receiving aggressive phone calls demanding that they pay their electricity bills via electronic wire transfer or a credit card. Customers are then told if they don’t make a payment their hydro will be disconnected.

Customers are asked to call a 1-800 number that connects to a fake billing department.

EnWin says they don’t conduct payment acquisition for overdue accounts in this way. Customers are asked to never provide any personal information to unknown people over the phone.

If you believe you’re a victim of fraud, you’re encouraged to contact Windsor police.
