ABSA-*********** - CANNOT CHANGE SURNAME - CANNOT CLOSE ACCOUNT

I've tried since August 2021 to close my account. Firstly, I tried to change my surname to my new married one - no success. Then I've decided to close my account. It is now 01 December 2021 and still not successful after numerous branch visits, emails and phone calls. Absolutely ***********. I once again received ANOTHER reference number today. Phoned complaints department again and according to them my account is closed - BUT 2 debit orders went through yesterday and today. How on earth is it possible? The consultant asked my contact number and confirmed he will get back to me today. Nothing yet. When I've asked for a Reference Number he rep**** that the system is down and he cannot give one. PLEASE CAN I JUST CLOSE MY ACCOUNT AT ABSA
