FNB Private clients useless service

FNB Private client account is the most useless account anyone can find when I woke up this morning debit order ran when I had no funds. So I quickly deposit money so my debit orders are covered at around 5 am upon waking up since account was in minus upon deposit my account was in positive again. Then fast forward 3 hours late the make the debit order bounce after my account was in a positive. Then I am told by so called private banker they cannot do anything about that. But they quickly charge me for bounced debit order they cannot help me in anyway but they can help them selves to banking charges very quickly and for an account where I pay more than R360 banking fees they can even notify my that a debit order will run. So what excatly is the purpose of this account. Nedbank even notified me with less charges than this. Really disappointing from a bank I have banked with for so many years after leaving Nedbank thinking I was coming to a better bank.
