Bad service..poor communication

Hi good day . I've had a cheque account with FNB trying to close the account I couldn't close it due to the revolving loan account. After settling all accounts with FNB still they did inform me about the cheque account that there's a outstanding amount.which I also settled immediately. They funny part is they informed me that I've had an account with wesbank phoning wesbank they said I've got in account with direct Axis phoning direct Axis no details showing an it's more than 13 years back ???also request direct Axis to send me settlement letter. The other strange thing is according the lasted credit report nothing or other credit report show any if these accounts . Cheque account. Wesbank account. . That's the reason after 5 years I've close that close cheque poor communication from FNB.
