Cheque account closure delay

I thought being a Private client at FNB will result in better service. Turns out that is not the case at all. I requested account closure at the beginning of July on my cheque account and spoke to Promise Dube. She requested that i pay R100 into the account as there is funds of 80 odd rand pending on the account. I phoned FNB today( 16/07/2019 ) at 16:00 to find out how far we are on the process and spoke to their manager, Zahraa Chopa, and she said that the account is not closed, because there is another payment of R270 (That includes pro rata monthly fees) that needs to be deposited in order to close it down. I think that FNB or Promise should pay this amount, as it's a lack of competence from their side. I will never recommend this Bank to anyone.
