Hassle to Close FNB Account

In the first week of March I called FNB to close my FNB account. The consultant confirmed it will take 3 working days and someone from FNB will contact me to confirm. Nobody from FNB contacted me and my account has not been closed. I already switched my Salary and Debit orders, so FNB must take note that I will not pay any additional banking fees. This morning I also received a notice that a debitorder did not go through and now I have unpaid debit order fees. I tried calling FNB but now you need the FNB app to be able to get through to FNB on any of the numbers and I already cut up my FNB card and deleted the app so behold I cannot speak to an FNB consultant. You can track my previous complaint in March to see that I did say I am cancelling my account.
