FNB rises again

Today has been the last straw, my FNB Card is with the legal department, and after I received an email from Se**** I rep**** and requested a payment arrangement of R1000 per month, he never rep****. Last month FNB took R 3740 from my account, and this month another R 3400 which I cannot afford. This morning when I phone Se**** he advises that my arrangement was not accepted, but he never responded to inform me. I have now confirmed and arrangement with him for R 1500 per month which he accepted but will not refund the difference of the R 3400 that was taken. There is now way that I can afford the R 3400, I have two kids and a lot of expenses to cover, how can FNB just take what they want??? This is not the first time I have had this problem, and now I am left with no other choice but to close my FNB account and move my money elsewhere just to be safe and not have them ***** my money every month! I need the refund of R 1900 this was error on FNB side!
