Poor client service

I have settled my two outstanding accounts with FNB in order for them to be closed. After I paid the settlement amount FNB charged bank fees. For accounts not used over 2 years. so for 2 years no bank fees was charged and now suddenly they charged after I have settled my account in order to be closed. So FNB than reversed the cheque account's monthly fees to close the account, but the Easy account has not been reversed to be closed. So I went in to the Branch to close it. Yet they tell me I must first settle the account before they can close it. So I explained the situation, showed all the emails from FNB where they have reversed the money to close the account. FNB struggled to get hold of FNB head office. so they said I must pay the outstanding amount. Yet again I do not understand. So I did pay it to close the account. Again there was outstanding fees charged again. I do not understand???? The service that FNB has given me is behind poor. It is one of the reasons that I have moved. So in order for me just to close the account an amount of over R200 was needed to be paid. I really wont suggest this bank to any person if this is the service given to clients!!!!!!!!!!!!!!!!!!!!
