Was checking email last night and saw one from Citi for my credit card that said my statement was available and the minimum payment of $20 was due. I paid this card off and it's been sitting in my safe since last month. I called them and there is an $810 charge to lens.com (contact lens) website. I cancelled the card and did a dispute. I went ahead and place fraud alerts on both me and the wife through the credit agencies. I also contacted my other CC and let them know about the other one being compromised and asked them to monitor my card closely for any suspicious activity and to call me if necessary. Is there anything else I should be doing? I've never had this happen before.
