Closing my FNB Account

I have been trying to close my FNB account without success. I was advised that the closure process would take 10–14 working days, and I submitted my notice before the monthly account fee was charged. However, I have now been informed that the account is still open.

Please can you advise why the account has not yet been closed and who will be responsible for the monthly fee that has been charged, considering that I requested the closure before the fee was due?
