Unauthorized Debit Orders

No FNB is my favourite bank, I used to get paid on my FNB account but almost the whole of last year always had debit orders of small amounts of which I wasn't aware of up until I needed my bank statement.

These amounts came out every month and if I had no funds, my account will be on a minus and had to keep reversing debit orders of which wasn't good for my credit record.. ended up having to move my salary to another bank because every month at FNB I would bw told the debit orders won't be coming out any longer but month after month I still had the same problem.

I tried closing the account but that wasn't actioned because of the minus, I have been getting paid on another account but still I get these emails and texts about the debit orders. Which makes me believe that even if I stayed at FNB I would still be fighting the same battle 13 months later!

I want my account back but I am hesitant due to these debit orders that just pop and they seem to be increasing. I don't like other banks...
