It's a scam.  Shows (613) 216-2172 "Ontario" on caller ID.  They are tryomng to get your credit card information.  File an online complaint with the FTC here:http://esupport.fcc.gov/complaints.htm

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!

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."

The call came in - Caller ID had the number and "Ontario".  I listened to the auto message and then pressed 4 to get the live operator.  Got a guy.  He started into his routing when i interupted and asked where they got my nimber.  He replayed that they do not have a list.  I started to then say take the number off the list - "What part of 'We do not have a list' do you not understand?" and then "If you don't want our calls then unplug the phone and shove it up your a**".

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.
