Warning - one of my Citibank credit cards has been inactivated for 'potential fraudulent activity'. When I contacted customer service I was told that they had another security breach , and that a series of accounts may have been compromised. So as of yesterday, they are inactivating accounts, issuing new acct numbers & sending out new cards.

So check your account(s). Only one of my accounts seems to have been affected.

The part that I find interesting, was that the cs agent said I could continue to use my card until I receive the new one.
