I have received numerous calls from this number. They call several times a day. Really very annoying. Tried calling the number back and it just rings busy. I don't bother answering anymore and just let it ring.

I pick up the phone - no one there ...

yes am reporting this to the phone company.

Call your phone company and ask if they can block the number.

Now the number is apparently out of service...and their website: www.kantar.com is not functioning...because it looks like they've changed their registration to a new domain:   Domain Name: KANTAR.COM   Registrar: ASCIO TECHNOLOGIES, INC.   Whois Server: whois.ascio.com   Referral URL: http://www.ascio.com   Name Server: APDNS1.GRPITSRV.COM   Name Server: NADNS1.GRPITSRV.COM   Name Server: UKDNS1.GRPITSRV.COM   Status: okascio.com is headquartered in denmark and germany...so they have moved to places where extradition is difficult...I'm going to guess this is a big scam outfit...if you get a call from them...report it to your local law enforcement cybercrime division...and the CRTC...   Updated Date: 04-apr-2011   Creation Date: 20-mar-1998   Expiration Date: 19-mar-2012>>> Last update of whois database: Wed, 19 Oct 2011 17:33:23 UTC <<<

This number has called numerous times during the past few weeks. We leave unknown numbers for our answering machine, but sometimes pick up repeat callers to tell them to stop.

I answered one call about a week ago -this caller asked me to take part in a survey about communication and leisure time. I explained I was on my leisure time and did not want to communicate with them. I asked them to take me off their list and stop calling. He said that was impossible, that the numbers were randomly generated.

The calls from this number continued, and I answered the third time they called tonight. I asked them to put me on their do not call list. I told them I was going to report them to the CRTC, they said telemarketing rules did not apply to them, they are not selling anything.

I checked the CRTC web site and see that market research and phone surveys are not bound by telemarketing rules. They are free to call whoever they want, they have no requirement to keep a list of numbers who do not want to be called.

They only way to stop this is to write your MP and complain to have the law changed to require all businesses who engage in unsolicited calling to maintain a do not call list.

You would think these businesses would do this just out of common sense.
