Call From "Visa/ Mastercard" Rep Looking For My Partners deceased husband (20 years). I asked where he was calling from and he said Canada. I said where in Canada and he said Toronto. I asked him who he was calling for, Visa or Mastercard ? Around this time he got flustered because I told him he didn't know who he was working for. Too bad he didn't know 613 area code is for the Ottawa region. He told me i ask too many questions and he hung up.
