Was just notified that Citi closed ALL my CC accounts. I've been a customer for many years and have some of my oldest cards with them. They can only tell me that it was for "security reasons" and that the decision is "non-negotiable." The rest of the info, they say, will be sent to me within 7 to 10 business days. Has anyone had this before? Is Citi taking a page out of Chase's book?
