Citibank Fraud Flag on Legitimate Purchase Forces Multi-Rep Authentication Loop

Citi flagged a legitimate purchase as fraud and required the cardholder to call in, but multiple service representatives could not complete authentication through the app, creating an authentication trap with no escalation path. The fraud false-positive combined with broken in-app authentication is a severe UX failure. No self-service fraud flag dispute or authentication bypass exists.
