FNB getting too comfortable on customers' accounts

My account was overdrawn by R41.10 during the night of the 16th October 2017. Upon realizing this, in the morning of the 17th of October 2017, I transferred R200.00 into my account to outlay the overdraft (of R41.10). I have now realized that FNB charged me R110.00 and the description is "#ITEM PAID NO FUNDS 1 ITEMS ON 17/10/" and the reference is "1 ITEMS ON 17/10/16" (copy attached). I ensured that I deposit R200.00 and that was way-more than R41.10 and I do not understand why FNB would charge me for that when I did not ignore it but ensured that I deposit money. How would I be aware of such a occurrence if FNB did not inform me and give me sufficient and reasonable time to make right what was wrong. This is preying on people and making millions from the people of this country. Let us say I was made aware that my account is overdrawn and I was given sufficient and reasonable time to correct the situation, what does not make sense is when FNB charges R110.00 for an overdrawn amount of R41.10. Something I consider just unfair. I would like my R110.00 to be deposited back into my account ASAP. I hope I will get my money back into my account
