Account closure turned to rocket science!!!

I'm so disappointed at FNB. I have been trying to close my account but they keep on sending me from pillar to post. I called in the first time to close my account they said they will process my request and close the account. After a couple of days, I called in the 2nd time to ask why my account hasn't been closed, I got a vague answer but now they tell me there are some fees that I need to pay which did not make sense as they never mentioned this on the previous call but however I made an immediate deposit for the charges whilst I was on the line, the banker acknowledged the receipt of the deposit and said she is closing the account. Few minutes later she says it is taking a bit of time, she will close the account and send me an email the next day to confirm closure of the account. Today the account is still not closed and the account is accumulating fees, so who is meant to pay for those fees FNB? A simple request to close an account, is taking you weeks to process.
