FNB the worst bank in the world

I'm tired of FNB just going into my account and taking my money without my permission.. With FNB once you make arrangements you think you safe but no as soon as money comes into your Account they take it but with me personally I have been banking with FNB for over 10 years and I think there service is purely disgusting solely for the fact that you will make arrangements and they will still come into your account and dishonor those arrangements I'm done please close my account . Who gives them the right to debit my account all the time
