wrong credit info provided to Experian and credit score agencies

I had a citibank card several years ago...last time a card was sent - I did not re-authorize the card because I no longer wanted it. However in Dec of last year you accepted an auto charge on this card that should not have been accepted as the account had expired a lont time ago. I did not know about the charge until I got a phone call regarding late payment. I then paid it promptly and closed the acct with your representative. You however reported my late payment and caused a degradation of my credit score. I would like this corrected. The mistake was yours in allowing the charge and I had no way to know a charge had ever been made. I no longer have the card and the account is closed now. please have a live customer service person contact me directly at ***-***-**** to get this resolved. The home number you have for this account was ***-***-**** and information is deborah hawkins ** Congressional court, Las Vegas, NV *****. Last four on the acct were ****.*Your customer service phone line is not helpful at all as there is no way to get to a live customer service person which I find incredibly useless!
