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.

Caller ID says Unknown Name, I called back and it says message box full.  No idea who it is.

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.

Receive calls from a toll free number and then when called back to check we are charged an international call fee.  We are on the DO NOT CALL list but apparently it doesn't matter to this company.  I usually do not answer unsolicited toll free numbers, but when we receive numerous calls from a particular number I sometimes check to see who they are .  Do not do this as we have been charged international fees on our phone bill.

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.

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**".
