Bank Charges for reversal and stop orders that was requested previously

End December 2022 I have called FNB and made a stop payment on an account and reversed the money as the supplier was paid via eft. So stop order means this will not happen again and paid for every reversal done. Now this month all 3 of those debited my account. Who is going to carry the costs of the reversal of these transactions? R90 per transaction. I am considering to move to another bank after years of banking with FNB and having a few accounts with them.
