Citibank AGAIN!? That's three hackings I know about and am sure there have been more. About three years ago, I had a Citi Card, I just thought I'd keep it in the safe for a backup. A year later, I get a bill saying I owe $300 for international phone calls to Saudi Arabia and some ski equipment in Washington.
I immediately called them and said I made no such charges and told them that Citicard is in my safe and has never been used, in fact, it's not even signed by me. But they kept saying "you must have used it somewhere". I asked them are you not understanding me? that card has never left the safe, ever. If there are any charges it's because your easy to hack and this is not the only time. I also told them to spend your money where it'll strengthen your security like better webmasters, trustable personnel, hire security experts. (I was pretty steamed!) I told them to cancel that card.
They sent me a form saying I'm not responsible for the charges and never heard from them again.
