Poor customer service

I have deceived close my absa cheque account because of the ******* debit order and cost of reversing and sometime charges of those debit order when there are no funds on my account are too much . Cresta at absa is telling nothing they can do to stop the ******* debit order and to close the accont until it is fully paid. How to i pay the account in full was these debit orders continue to increase the money
