I also have gotten calls from them, threatening ones.

Got a call from this number tonight. They knew my first and last name and it sounded like a woman making her voice high pitch. I said wrong number. Who IS this?!

When I called it back it said the number is for outgoing calls only.

They called me 7 times yesterday, but never answered. Who are they?
