What the Call Sounds Like
Most calls are the same. It’s not a real person. It’s a robot voice.
Here’s how it goes:
- It says it’s from a power company.
- It talks about cheap power plans.
- It asks if you own a home or rent. Push 1 for home, 2 for rent.
- If you pick home, it might ask more. Like your area or power use.
- Many hang up here. The call ends if you wait.
It calls any time. Day or night. From big cities like Tokyo to small towns. Even places like Aichi, Mie, or Fukuoka.
Why do this? Scammers want your info. They sell it. Or push fake deals.
