FNB Evaton Plaza refusing to open a Bank Account

I walked in to a Branch on the 21st of October 2017 at 12:18 and I was assisted by a lady called Miss Busisiwe Khambula/ Khambule I am not sure because she was even refusing to show me her name Tag, I wanted to close an existing account because it gave me problems with unauthorized debit orders, I even explained to her that I've tried numerous times to stop those debit orders but they keep coming back but she refused to help me, I asked her to update Customer Remarks and state the reasons why she is refusing to assist me and still she refused, I asked to see a Branch Manager she picked up her phone and called someone they talked on the phone and when she drops her phone she insisted that I use my existing second transactional account, I then asked her the reasons why she is refusing to update Customer Remarks, and she said "it costs the Bank money to update Customer Remarks", that's when I began to realise the reality of a pethetic service I am being given, the lady was not even ashamed to lie through her teeth... Since when it costs FNB money to update remarks... I feel like FNB Evaton Mall is the worse of them all and with such Branches, FNB can never reach its goal of being number 1 Bank in South Africa.
