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?

Phone rang, I always look at the id first, it was (613) 216-2172 in Ottawahull, ON.  I know no one there so I ignored it and the phone stopped ringing.  In a few minutes, the message waiting light on the phone turned on indicating that a new voice mail was stored.  Checked vm, silence, but I saved it anyway just in case.

Received several calls from Ontario, CA (613) 216-2172 with no message.  Called back and no company name was given, so I hung up.  Now I'm charged for two international calls to Ontario, Canada, which totaled over $6 with all the taxes and carrier cost recovery fee.It's a scam.

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.

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.

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."
