This is not the way of doing things

I recommended FNB to my organization because, my father used FNB, he trusted them and so I trusted them also. Never did I expect that one day they would do me like this. First. I am failing verification checks when I am trying to register with CSD and I don't know what happening as I am sure I am giving the correct account number, the problem persists, CSD sends me to the bank for the account confirmation and to check on their system "organs" if I remember correctly how Account details are captured maybe that why it is coming back as failed. We go to the Bank on the 19th of December 2024 and we are met with great warmth and given the best customer service. Account is active everything is okay. On the 14th of January I received a sms stating our account has been closed due to balance due, I must contact some lawyers. FNB has not once made me or Mr. Madlala our treasure aware of any balance that we were owing on the account. No communication what so ever was made even when we were at the bank on the 19th nothing was spoken with regards this matter and FNB first step to resolve a problem with us is to CLOSE WITHOUT INFORMING US!!!!!!! Send the account to some lawyers and let us know through sms that our account is closed. I expected better from you, even if we had to part ways this was not the way to end our relationship. Steps should be placed and followed before reaching reaching this stage. You should have given us the chance to fix it without involving other people, You took a chance from us to make things right before closing the account
