Called at 9:04pm July 4th... These calls really P...sng me off. Who can I report this to to block the calls.

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.

Called six times in a row, after I answered the first call.Is there a way to block this?

The number is for;Norsask Consumer Interviewing Services LtdI 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.
