Two calls right in a row - no message left. After first call went to answer machine with no message, no less than 10 seconds later the 2nd call came in, same thing.

It's not Yellow pages it's a company called Advanis market research. They say they are conducting a search market research study or at least that's what they are saying on the auto answering machine they have set when you call the number, it also says you can contact them at  1 888 944 9212 and they give a mailing address located in Edmonton Alberta.http://www.advanis.ca
I have no idea how they got my cell number and why they keep calling and never leave a message, it gets annoying.

These people have somehow managed to get my pay as you go cell number and call every few days.  I have left them a message to let them know I am not interested and hope they stop now.

Just called them back said they are doing a survey on behalf of WCB. I was just receiving wcb for a back injury. Hope this sheds some light

I called the number back after blocking my number and received a message that the call came from Advanis Market Research (a legitimate company wanting to do a survey).  www.advanis.ca.  Sorry, but I don't have time for this.  Number now blocked.
