FNB - legalised Theft - unbelievable

We have had a REVOLVING LOAN facility with FNB which was cancelecd AGAINST THEIR OWN TERMS AND CONDITIONS. The debit order hance was canceled. BUT FNB CARIES ON AND ON DEBITING OUR ACCOUNT EVEN WE HAVE SETTLED THE ACCOUNT 2 MONTH AGO. More and more and new fees turn up. Nobody competent can be contacted. This in my opinion is simply legalized THEFT - "How can we help you". We now found an option "settle and close" for this account. We have paid the "black TAX" but I am sure they will try to debit (*****) again - after being a client for more then 30 years FNB you should be ashamed of yourself
