Unfair Nebank

The Nedbank's low balance notification is misleading. I am certain nedbank is using it to their advantage. On the 28th February at or around 08h00, realising my Cheque account is overdrawn and my debit orders will be reversed, went to the ATM and made a deposit to correct the negative balance, LOW BALANCE notification was at that time not delivered to my phone. An hour or so after the deposit, the low balance notification is delivered and 12 hours later 3 notification that my debit orders were not paid and with it came R150 fee for each failed debit order. My debit orders goes off on the 25th and i just thought they went off already. I am not even sure going the Ombudsman route will relieve my anger with Nedbank or Just take my accounts somewhere else.
