If they are indeed based in Canada -- filing a complaint with the FCC or FTC won't matter, will it??  The U.S. agencies would have absolutely no jurisdiction. I am very annoyed with these calls, as well.

No one is on the line when I pick up. I put them in my reject list; they still call. How do I get them to stop?

i didn't answer the call.  It appeared they left a message, but when I went to listen to my messages, there was nothing.  just a blank.

File a complaint with the FCC Online here:  http://esupport.fcc.gov/complaints.htm  These people should be shut down because they use automated machines and do not allow you to tell them to stop.  Their mailbox is "full."

Have received numerous calls also.  I called back from my home phone and got a message that the number was disconnected.  Called from my cell and work phones and got a message "I'm a big jerk and I leave erroneous telephone calls with no messages".  He is a big jerk and he does make erroneous telephone calls with no messages.

A long-winded recorded message.  I left the phone on the desk while I worked.  After about 10 mins. I picked it up they were just winding down, asking if I would write my congressman, etc. about health care.  Seemed to be AARP or AARP affiliated.
