Fnb Charged R620 for debit honoring so in total I paid over 1000 in fees only

Yet another problem with fnb, I had debits that they honored which I didn't ask for and they charged me R620 for that, which is ridiculous, I did not ask the bank to honor my debits and worst case if it went unpaid I would of asked the debitor to debit on another day, it's a rip of especially on a bussiness account
