They called me looking for someone else. How they associated my phone number with another person, I'll never know. I called and told them he wasn't at my number and to please take my name & number off their list. They said they would "remove it right away" but that remains to be seen.

These idiots have been calling here for a year.
They have the wrong number.
No one there has the intelligence to grasp that.
You think they would notice that they've made a thousand calls without ever getting to talk to the loser they're looking for.
But they don't notice.
So they keep calling.
Morons.

I called the number back and requested that they STOP contacting me. They are a debt collecting service who were trying to reach the previous owners of my phone number. Was told it would take 24 hours for their robo dialer to stop. Hopefully this is true.
