#Item paid no funds

Good morning.

I am not happy with these FNB charges and the last time I queried these charges I was given some explanation I did not understand.

At the time of the purchase I had money in my account and I do not have an overdraft facility but FNB is still charging me R150 twice for #Item paid no funds?

Why is it that I am being charged R150 for #Item paid No Funds 1 MS on 20/09? Why is this appearing twice?
