Call received.  As usual, NO USEFUL call display information.  Let it go to the answering machine; as usual, NO message left.

I called the number back.  I heard a recorded message which identified the number as belonging to a company called Abingdon Research.

Here is information for Abingdon Research:  http://www.abingdon.ca/contact-us/

You just tell one Market Research company to NEVER EVER call you again.  Another one calls in its place.  It's ridiculous.  It's time for these USELESS companies to reform their practices.  At a minimum they MUST not call anonymously - the call display should show something other than generic.
