Account closure nightmare

I have been trying to close a cheque account for the past 2 months, and all I get is "account closure has been escalated" from the consultants; however, come month-end, the account is owing bank charges. This is unfair because now I must keep paying for a product that I specifically stated that I no longer require, but it seems like FNB is using it to get money out of me. This is starting to feel like I am being ****med out of my hard-earned cash.
