Terrible service and item unpaid issue

Terrible service from fnb please look at your bank statement for charges, I spoke to the secure chat and on the 22nd of February an amount was taken off and a transfer was done for the debit order fnb mentions there was no funds in the account and charged an additional 150 for item unpaid which is totally unfair to the customer! In a time of a pandemic your own bank robs you as well I have mentioned the issue with the credit card payment still not resolved as the max amount has set and this does not go off as scheduled on the app and causes confusion I request for the item paid to charges to be reverse and for the issue to be rectified this is totally ********* business practice! Be very careful with this bank! Someone please call me urgently as I am a very unhappy customer! ***
