Bank statement misleading and requesting a exorbitant amount

I am not happy with Absa, my Absa account has been dormant and I have received a statement last month via email statement only show that I have -R40 on the account, I went to the bank yesterday to pay and close and I got a printed document stating that I owe the bank R1030.24 bank charges while the statement they send via email states R40 how did it increase and why the amount they gave me is not on the statement!! This misleading and not ethical nor fair to me as a client, I am thinking of taking this to the Ombud! This is not the first time they make me pay an exorbitant amount of bank charges. I can't close the account and I don't have that amount of money and I am told it will keep on increasing yet the account is dormant and have a hold on it.
