This scam starts with a scary message about money. It looks like a bill from a name you know. Maybe Norton, McAfee, Geek Squad, PayPal, or Amazon. The trap is the phone number. It does not reach the real company. It reaches the scammer. He waits for you to call.

Subject: Your order is confirmed. Thank you for your purchase. Your Norton 360 subscription has renewed. Amount charged: $499.99 to your card on file. Order #NRT-90381. If you did NOT make this purchase, you must call our Billing Department within 24 hours to cancel and get a full refund. Call now: 1-888-555-0147. This charge will post to your account today.
This is a made-up example to teach you. We will never show you a real person’s message.
“Amount charged: $499.99”
The big scary number wants you to panic. It stops you from thinking.
“you must call our Billing Department within 24 hours”
The deadline is fake. It rushes you so you will not check.
“Call now: 1-888-555-0147”
This is the trap. Real companies do not work this way. The number reaches the scammer.
“get a full refund”
The refund is the bait. On the call, they go after your computer and money.
“Order #NRT-90381”
A fake order number is added so the message looks real.
It scares you about money. So you want the charge gone fast. When you call, a stranger guides you. They ask to see or control your computer. They say it helps them send the refund. Then they pretend they sent too much by mistake. They beg you to send the extra back in gift cards. That trick is the real scam. There was never a real refund. The gift card money is gone for good. This is true even if no real charge exists.

A real refund never needs your computer or gift cards. If someone asks for either, it is a scam, every time.
