FNB is *****ing my money by not downgrading my account as requested!

I have been trying since the beginning of June to change my FNB premier fusion account to an easy account as I no longer need the services of the premier account and don't want to pay the banking fees for it. I told them that it is urgent as I am immigrating to New Zealand so they wont be able to reach me on my nr so I need it done before I leave South Africa. Numerous agents I spoke to reassured me that it will be done within 10 working days. It is now end of July and this is not yet sorted out. I have paid account fees twice now since requesting this change! FNB is now *****ing my money as I am paying account fees for an account I don't need. All I want is to downgrade to an easy account! Secure chat is a joke and does not work, you just go in circles with your query! It is 2024, it can't be that difficult to do with the technology available!
