Not the bank it used to be!

I am appalled at the lack of service from FNB. I have been with FNB for the past 15 years or so and opened my business account with them as I have always believed they were the best bank but this has completely changed. Four days ago I had settled my loans but noticed the accounts were still there so I did as the app instructed and downloaded the settlement quote, paid it but the email address provided for proof of payments no longer exists. I was told today by a very rude consultant that the accounts will automatically disappear. I tried to settle and close a revolving loan but the app will absolutely not allow it. I was transferred to 4 people as each person I was directed to was not the right department. Once I finally spoke to the right person, her first and only response was "Please go into a branch if it's not working" and then complete silence. No effort to ask me questions or try to understand what the actual issue was. I am still in shock. I am seriously debating whether to close my accounts with FNB once my accounts are rectified.
