At 4:30PM EST today, 15 August 2007, I logged into the CitiBank website for my CitiBank MasterCard (referred to from here on as CB MC)and was surprised to be presented with a blinking red notification that my card had been flagged for "suspicious activity". I was directed to contact CitiBank customer service. What follows is my efforts to determine what has happened.
