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.

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?

Have no idea who this is.  They leave no messages.  Calls at different times of the day.  Would like for them to stop.  We do not answer, but the phone ringing with unwanted calls is annoying.

I keep receiving this call. I called it back and it says the number is disconnected.
Ottawa  ON  (613) 216-2172 appears on my caller ID

We have received mult. calls from phone #(613) 216-2172. When my husband picks up there is dead silence on the other end. We are listed on the do not call list. This is becoming very annoying. Who ever is doing this...oviously has too much time on their hands.  If they would only redirect this negitive energy to positive energy.... this crazy world we live in would be a much better one!
