How do you get removed form the call list??

I received a call from this number. It showed the number as the caller id(?). After it rang three times, I answered but there was no one there. I have no idea who called. There was some clicking sounds too.

I also keep getting calls from this number. I found out it is some kind of energy/electric company.

This is some kind of scam

They would be much better off sending out a mass-mailer -- a professional looking promo-brochure, or something similar, outlining, explaining and advertising their services.

Cold-calling DOES NOT work. It went out the door years ago ... get a clue.  

I do not answer when they call ... almost everyday ... so stupid.

They can call from now until the cows come home ... like most people, I will not answer the phone.
