CLosed account open

I again receive a call from ABSA inquiring as to how I pay my revolving account to which I again answer that the account should have been closed as I do not have an account with ABSA. He asked me to hold the line and after 5 minutes of music he failed to return to our conversation. I went to the Fourways branch of ABSA on 19th September 2018 to close my cheque account and also asked them to close all remaining accounts as I was transferring my account to another bank. At the same time I closed both my credit card as well as both my wife’s credit card accounts. They said that everything was in order following any fees that were payable at the teller and so I left the branch under the impression that all accounts had been sorted. Today was my second call regarding the revolving plan and both occasions I stated that this account should have been closed as said above. If for any reason this account is active it is due to the inefficiency of the ABSA staff as they informed me that all accounts were closed. Please sort out this account and close it, I will not pay for any fees that is due after the 19th September as the account as said above was a zero balance and should have been closed.
