Unfair charged penalties

On my account ending with ...9993, I was charged R125 on 23/05, and R125 on 22/05. Reason being #Items paid no funds. Furthermore was i charged R250 on the 27/05, again R250 on the 28/05/2020 ; same reason #items paid no funds. If you look closely on my complaints history i have been complaining about the same nonsense for a while. To a point i have ask for my bank charges to be deducted on the last day of the month but looks to have not happened. I am sick of you guys ripping me off. So i request those funds to be reversed to my account. If you dont, then i will gladly submit my new banking details to my HR and close off this account. You should be ashamed doing such during a pandemic.
