Account not closed

I last used my discovery bank account in 2021. Since then my account accrued almost R10 000 bank charges. My father accidentally made a payment into this account, obviously which we cant utilize at the moment. I decal that I did call Discovery on 2021 to close account, however they deny this. I want the charges from 2022 till now be reversed so that I can access the deposited funds. The funds where given so we can buy groceries for month as I have been hospitalized. Discovery bank just says that they cant do anything
