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?

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.

Hi... I like to knock on doors...or just phone at random...I don't care how many people I bother...because I don't give a sh*t about you... or your wasted time.I just want your business...and I don't want you to bother me...especially if you don't like my service...and you wont like my service...but I wont be guarranteeing it anyway...and if you think you will be able to contact me... Ha,ha,ha,ha,ha...

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

Just called up this number (604) 998-1404 and a lady picked up the phone. I told her to remove my number from their list and she promised to do so.

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

We are getting calls from this number, once we answer and wait 10 seconds for a response all we get is a buzz and a female voice says thankyou.
