[quote=CA renter]FWIW, we had the same thing happen to us with our Citibank card. One day, it was declined for no reason. When I called them up to ask why, they told me that there was a hold on my card because of some sort of fraud (someone tried to use it illegally???), and a new one was on the way.

This happened to me a while ago too after BofA took over my Citibank cc. They told me that the card was “compromised” and that it was part of a large database of cards #’s that was hacked into at some merchant and weren’t allowed to tell me who it was. I used that card for everything so it could have been anyone. There was never any strange activity on the card or new card before/after the incident.
