Absa current account

I have been querying my account with Absa since April 2018 and to date no feedback. I am being charged on a account that I no longer even use. I went to Jacaranda branch to close the account and was informed that I cannot close the account as I have active debit orders on the account. I have logged queries with regards to this and all my debit orders have been cancelled since April/May but I am being charged +-R150 for debit orders and monthly charges. The account is now almost R5000 in minus and still no resolve to my query. my query reference number is Case Ref No. ********** and I get no response from Zimkita Cewena either.
