RCP FEE for PLS + Account overdrawn charge

I looked at my bank statement this morning and notices a #RCP FEE FOR PLS deduction on my account. I have no idea what this deduction is, so using google I found that this is a fee you pay when your debit order doesn't go through in time.<br> Checking the bank balance a few days before this deduction, I did have sufficient funds in my account, I always ensure that I have money in my account on time for deductions. Also, i received a text stating that my account was overdrawn. I check and then transferred from another account to bring the balance back to a positive one. the next day i get another text message stating that my account if overdrawn again! So I log in and it was FNB charging me for the being overdrawn the previous day!! How does that logic work!!<br> I used to be a great advocate for FNB services but I think its time i search elsewhere for my banking solutions.<br> I want these errors rectified and my money back, for all these fees that were deducted when I had funds!
