False listing to credit bureau

I cancelled my Neotel account in 2013. My bank account was debited for the last time and my Neotel account closed. I assumed everything was fine. <br> I am in the process of applying for a bond and the bank has come back saying that Neotel have listed me with the credit bureau for an outstanding account. I phoned to to enquire and they stated that they incorrectly short debited by account by 84 cents which they never informed me about and incorrectly sent my details to the credit bureau. <br> I had absolutely no idea of this and would never have known if I wasn't applying for a bond. I have been phoning since the 18th of June stating that I urgently need a letter to say it was their fault and my account is fully paid and closed and I am still waiting. <br> I have never in my life paid anything late and make a point of ensuring I have debit orders on everything so everything is paid on time. I never thought something like this would happen to me as I am neurotic when it comes to paying things on time. It is totally unfair that this has happened and his may affect my bond application which is totally unacceptable. <br> I want an answer from Neotel on how they are going to clear my name.
