Have no idea who this is. ?They leave no messages.  Calls at different times of the day.  Would like for them to stop.  We do not answer, but the phone ringing with unwanted calls is annoying.

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.

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.

Today, something about reducing interest on a credit card.  Just hung up to not waste any more of my time.  BTW I do not own a credit card.  Obviously a scam.

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:
