I won't answer if the Caller ID reads "Unavailable," and I don't recognize the area code.  No message left.

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.

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."

didn't answer when i picked up.  afterwards,  i accidentally pressed to the number to call back.  turns out, they're some sort of loan modification co.

They keep calling me. I say "Hello", they say nothing. they annoy me.

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.
