Credit card cancelled, yet reported

I cancelled my credit card so long ago that I cannot even remember the details. Today I note that Nedbank reported me to the Credit Bureau for a R27-00 balance which Lynette says is greenbacks fees. She confirms the account is not active, but has never been cancelled as was instructed by me to the bank. Lynette just says I must cancel the card again. My question, Nedbank, can you not trace cancellation documentation and see that my instruction was given so many months ago? And reporting me for R27-00 without a phon call, really?
