Hello @Joe Vodraska,
Thank you for reaching out to the Community and telling us about this issue. I'm sorry to hear you're running into this problem. Which troubleshooting steps have you already tried? Is this for a Citi Credit Card or a different type of Citi account? Are you getting the CC-502 or a different error? If its a different error, what is the error message and/or error code?
Thank you.
