A voice says your electric bill is overdue. They say the power goes off within the hour. The rush is the whole trick. A real utility never works this way.

Hello, this is the billing department at your electric company. Our records show your account is past due. Your service is scheduled to shut off within the hour today. To stop the shutoff, you must pay $312 right now. We only accept payment by prepaid debit card. Please go to the store, buy the card, and stay on the line with me. Do not hang up or the technician will cut your power.
This is a made-up example to teach you. We will never show you a real person’s message.
“shut off within the hour today”
Real utilities warn you on paper for weeks, not in minutes.
“you must pay $312 right now”
A surprise demand to pay this instant is a scam sign.
“We only accept payment by prepaid debit card”
Real companies take many ways to pay, never just one odd one.
“buy the card, and stay on the line with me”
They keep you on the phone so you cannot stop and check.
“the technician will cut your power”
No real worker waits on the phone to cut your power.
It mixes fear and a clock. Losing your power feels like an emergency. The rush keeps you from stopping to think. You cannot check your real bill in time. The scammer wants the money gone before you can verify.

Real power companies warn you on paper. They give you weeks of notice. They never demand instant payment by gift card, prepaid card, wire, or an app.
