Just a silent or hangup call.

Just received a call this morning from this number. ?I do NOT answer any calls where the ID is "Blocked", "Unknown", "Unavailable", Anonymous" or "Out Of Area" or I don't recognize the caller ID.  The caller ID on this call was "OTTAWA   ON", no name and then the number.  Since we know people in Ottawa, I called the number back twice and both times I received the, "This Number Is Not In Service". "Please Check The Number and Dial Again"!  From what has been reported here, I see that it s a scam.

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?

Call on caller ID called it back, got a bill for a call to Ottawahull, On

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.

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.
