Closing an Account is Impossible

I have a revolving loan that I closed on the 4 Jan 2018 i got told to pay R0.20 for them to be able to close the account which i though was petty so I made the payment. 7 Days later nothing, I phoned again got told the same story I logged call through online banking the escalated the query. I got billed R0.16 interets for the account for Feb, I phoned again today where the lady told me the account was scheduled to be closed on Thursday 22 Jan already but it is not closed. The customer service in the past year with FNB has gone to ****. I think it is time to start looking for a new Bank.
