Absa Cheque Account

I have a Absa cheque account which I have tried to close off online and was unable to do so. I also called in to canceled the debit orders and was told that it will be done. My account which hasn't been receiving money for 3 months has now been handed over and the amount is R5989 is due for a cheque account that not even 1 debit orders ent through. I have admin charges of about R1200 per month which doesn't make sense. I don't have that kind of money.
