Citibank Credit Card Complaint

Citibank Credit card department,

Billing statement New York

I was notified by Citibank that my universal card payment was past due. I never received the statement. I personally visited the nearest Citibank office in - - to request a copy of the statement so that I could review it and make immediate payment. An official at this branch advised me that they did not have access to this information and that I would have to call Citi directly. I called several contact numbers but the only response was that this was an attempt to collect a debt and how would I pay it? I have been unable to contact anyone at either Citi or AT & T Universal Card to request a copy of the statement so that I can review it and make payment immediately.
