I had that call from this # a couple of times. ?I checked my call display and I just put the volume to the highest on TV (it wouldn't hurt my  hearing because I am deaf!) and held the phone receiver to TV.  I haven't received that # since!  I keep hoping!  Before I registered on the "Do Not Call" list last Oct/Nov 2008, I used to receive average 15 calls every day.  Crazy, huh?  Then in January 2009 (from 20th to 29th), then I received the calls again till I got an idea to put the highest volume on TV.  Then I hardly receive any calls except for my friends.

Have received many calls from (306) 664-7364, always late at night when everyone is asleep. I just discovered a phone number which I called ans told them to get my number off their list.PHONE 1-(306) 652-5160 YOU GET A  RECORDING, PRESS NUMBER 6 and you get a human on the line. Phone in business hours 9 - 5 Saskatchewan time. Give them hell, they do not go by the national Do Not Call List. They admit that they make late night phone calls. They should be stopped.

The number is for;
Norsask Consumer Interviewing Services Ltd

I don't know why they called but it is one of their numbers in SACK.

You could call your local authorities and complain. After you call them enough times they will contact the company and inform them of harassment.

Called six times in a row, after I answered the first call.

Is there a way to block this?

They don't give up.  They asked if I wanted to take a survey and I said no, but they keep calling!Get selective call reject from your phone company and put this number in it.

she called me 4 times and she has real mental problems she told me she would keep calling me until i answered her questions
