Payment bundle fees cannot be explained. Fraid from FNB.

Just had the most exhausting secure chat. Fnb keeps digging a hole in my account even when I'm trying to avoid going to the next payday in a negative. There is a new charge this month "payments bundle fee" that has never been there before to the value of R140. No one can explain what it is for and I want ir removed. Why would I be charged for using my account exactly how I'm expected to use it? What is the account fee for if I must pay so much just to make payments? Where is this charge communicated?? You guys just be charging anything you can. I pay way to much in fees on my premier account and honestly I cannot do this every month anymore. Last month my account was in a -590 in just charges, with some not even making sense but I did not address it and told myself I'll keep account clean and see this month. Now fnb came back again with brand new charges. I need these reversed. Payshap is free, and I hardly use immediate payments as they cost a lot. So where the hell is this payments bundle fee coming from? Your agent couldn't answer or break it down meaning it is *****. I must go through each item on my statement now because I cannot trust my own bank. I'm definitely shifting my salary to my other bank this month. Fnb has ill practices. Sies!
