Citibank Credit Card Complaint

Citibank Credit card department,

Identity theft / Fraud / Embezzlement Virgin Islands

Citibank has seemingly had a major breach in their security system. I received a fraud alert call about a new card ( that had never been activated ) about a charge made from another country. I received the new card 3 days ago, after receiving a notice from Citibank 2-3 weeks ago that they would send me a new card due to a possible data breach. If the new card, which I had never used and had not activated, was used fraudulently, then there has to a breach either at the Citicard level or a vendor that they use. I am very concerned about this level of a breach. My account was closed but in my mind the integrity of Citicard 's security system is in question.
