Well, they keep calling and they said they are the head office of Visa and Mastercard. They gave me the phone number and I called from the other line while they were on hold. I played dumb and the guy said I was wasting their time. Funny. Anyways, I said I called his number and was a unidentified phone number. We end up arguing on the phone while I played dumb and I told him I know you just tried scamming and called your number, he automatically hung up on me. Can't wait for the next person to call me. :)
