Impossible to close account

Hi Standard Bank! We started our relationship in 2009 when I came to Souith Africa as an international student. You stood by me through my studies and my years as a postdoc. In November 2018 it was time for me to move on and I left South Africa. Leaving you, however, was not so easy. I tried to close my account, but you told me it could not be closed due to payments I had done more than a week before. So you gave me lots of paperwork to sign so that my husband could close the account after I had left. My husband went to you a few times, but you refused to let go. We contacted your customer service, who were very concerned about WHEN and WHERE my husband had gone to see you, and not with actually closing my account. Today, I received a bank statement from you, indicating that my account is still open 2 months after I tried to close it. And so I try to contact you here, seeing as contacting you directly clearly does not work. Please understand that I will probably never work or have an income in South Africa again. The only thing you will achieve with keeping my account open, is having an account accumulating a negative balance that will never be paid. So please close my account. No, I cannot come to see you as I left South Africa in November. No, my husband cannot come to see you yet again as he is leaving South Africa, too. Please just do what I asked in November and close the account. Thanks.
