Who called from 6502301969

I don't know who they're looking for, but it ain't me.  

I pick up, say, "hello", hear the "pause" that lets me know it's an auto-dialer, and I immediately hang up.

Don't call me if you can't even be bothered to be on the line when I answer.

Constantly calling from different numbers

Total dipsht foreigner calling... harrass the crap out of him!

They keep calling my home but hang up instead of leaving a message.

I've been getting calls from this number for 3 years, at LEAST 3-4 times a month. Every time, i ask kindly that my number is removed from their computers and they say that it has been.
Today, I received a call (they were a week off schedule!!) and spoke to a middle eastern man. I couldn't understand a word he was saying so i asked to speak to his manager. He put me on hold for about a minute, and the same man was trying to tell me that he was the supervisor. I asked to speak to the highest ranked individual present in his office, and he put me on hold again. Then THE SAME MAN answered and said he was the manager of the office.
I know these [***] all sound the same but this clown was trying to impersonate his manager and his supervisor.
Could I take legal action on terms of harassment and the fact that he wouldnt transfer me?
