Someone claiming to be from the Fraud department of Mastercard and Visa wanting to know if I had organised to make a $2,000 payment to a window and glass company and that they needed to know if I had and if not what bank was I with and what account was the card linked to - when I said well if you are calling from the Fraud department you should probably have all that information already. Quite insistent that I needed to tell the information so they could verify that it was correct so they could put a block on the card - in the end I said I will chase it up at my end with my bank to see if there had been an attempt on my card, funnily enough when I tried to call the number back it was disconnected.....
