I've a call display and didn't pick up; so far one attempt only

I keep getting calls from this number. When I answer I get a few seconds of silence, and then what sounds like a recorded female voice says, "Good-bye"

Scammers. Call block.
You answer and guy laughs hysterically like mad. I hung up.
Call block.calling the police next time. This is harrasment.

I would like to send a bomb to these people.
I don't know who they are but am not interested in anything they are selling.
If I pay for a phone line, how is it I can be subjected to this harassment
without recourse?

same, call, no one responds, then thankyou. someone please stop this harrasmment

Do not call list appear to not interest this firm. They may be a good firm that has chosen a bad way of finding new clients. Perhaps everyone could phone them one after another until they see the errors of this system. A hundred or so calls a day might do it.

This is an annoyance and the perp should be tried and subject to harassment as punishment.  

I just got a call , the 3rd.I live IN A BUILDING  with electric heat !!!. I also get calls from heating and plumbing in north van.He always pretends he didnt know I was the same person he called 5 other times.   who would use such a dumb company?

Looking for owner info.

Same as previous comments, this person is rude and before you said anything he cut you off
