This number also called me after 9pm and when I started to say I wasn't interested the female cut me off, was very rude and then hung up on me. This is why we need one of those 'no call' registries, so we don't have to put up with 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.

Just got a call from these nimrods at 11:23pm. I asked the guy "are you serious"? and he answered "yes maam" timidly, and when I asked "do you realize what time it is, he smart-a..ingly answered "9:23pm maam"....wrong dumba**, it's 11:23!! so I asked for a supervisor, you can reach them at +1 866-652-5160 and speak with a supervisor to be removed from the list...geez

I think all this flow of numbers, can only come from the phone company itself, as you see them changing phone numbers, and there are a great many phone numbers of them. Who can afford himself to have so many phone numbers, if it is not from a phone company itself, or from a few of their employees.Have a look at the List of reported phone numbers:http://800notes.com/AreaCode.aspx/1-888

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

Is there a way to block this?

This number is listed as a teleReasercher.  If they are a ligitimate RESEARCH COMPANY then they can legally call until 10pm respondent time.  However there is a new list being created at the end of this month on the CRTC site to have your phone # blocked from TELEMARKETERS.  There is a difference.  But you should all go to the CRTC site to read the rules and regulations for having your number removed from these companies.
