ABSA refusing to close an account and continuously charging bank fees

Well over 3 hours on the phone with Premium Banking and General Enquires seeking resolution. Absa, Last year in Dec I went to the Greenstone Branch to close my accounts, as I have moved to FNB. My credit card was closed, but I was told that my cheque account could not be closed pending resolution of outstanding transactions from Uber. There were sufficient funds in my account to cover this. I immediately contacted Uber, who has advised that there are no holds, reserved funds or outstanding transactions on my profile. In the meantime, I have been paying ABSA monthly banking fees, as well as some ridiculous Credit Life Fee! I have tried repeatedly to call, but as always I am transferred from Pillar to Post with no answers. I don't know how else to communicate with ABSA, but in case you're listening. I want to close my account! The Greenston Branch is a nightmare, no one at either Premium Banking or General Enquiry can even transfer me to the right person.
