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.

Received a call while driving and there was no one on the other end.  The Caller ID indicates that the origination is in Canada.  I do know that a lot of fraud is now coming out of Canada, targeting people here in the US.  The most often used is by mail and includes a large check that is drawn under a legitimate company name and a phone number in Canada to call to inquire how to get the money... which involves sending money to them for "taxes" on the "winnings"...

Though I have tried to "Call Block" this number through ATT, the service will not allow me to do so!

I picked this call up by accident, as I was expecting someone to call.  When I just heard dead silence on the other line, I checked my caller ID and realized it was a dumb telemarketer.

Have received numerous calls from this number.  Last week my wife told them
to stop calling us as we were not interested.  We then received two phone
calls at 4:20 and 4:20 a.m. on Saturday, March 21st with them replaying my
wife telling them not to call us.  This number needs to be investigated and
shut down by the Canadian Government.

called me 3 times today.    caller id' the number.   i don't answer any calls that i don't know who they are.

Received this call 2 days in a row.  Yesterday i pressed one to talk to somebody, told them I'm on the Do Not Call list and they promptly hung-up.Today, i pressed one again, when I inquired as to their company name they promptly hung up again.Very dishonest to say the least.  Not sure what action I can take with no information.
