I keep getting hang-ups from this number every day, some times three times a day. They leave no message and I can't find any information about it.

Different people from the same number called and left a message.  One was female the first day and then the second time it was a male voice.  I did not pick up either call.  The message was as follows, "Hello? Is (my full name) there? I'm looking for (my full name)".

some guy wanting to know if will support PM Stephen Harper in next yrs election.  When I wouldn't answer he rudely ended the call.  Just weird.  

Calls daily.  Doesn't leave a message.  I have blocked it.

frequent calls from this number without any message

Getting fed up with this caller.  Keeps phoning at least 5 times a day, hangs up when answering machine kicks in.  Tried blocking it but it still persists.What is the nest step? Anyone?

I called this number back after it appeared on my call display (I didn't answer, and they did not leave a message). it is "voter outreach for Prime Minister Stephen Harper".
