12 Business days and counting to close my account

I have paid off my credit card account on the 22nd of September 2021(this is when the money cleared on Absa's side) I phoned in on the 23rd of September 2021 to find out what is the status, they informed me that the account is closed and their Admin Department will send me the closure letter as well as the paid in full letter, the account closure request was sent on the 27th of September 2021, I phoned again on the 27th of September to find out the status yet again and was informed that I need to wait another 5 - 7 Business Days. I phoned again on the 5th of October 2021 to find out the status since I still have not received my closure letter, I was then asked to wait another 2 - 3 Business Days, I then phoned again on the 7th of October to which I was informed that the account was only closed on the the of October (10 Business Days after they payment has cleared) I then requested the status of my closure letter as well as the paid in full letter, a lovely lady was then able to help me by contacting the Admin Department and they informed her that I will receive the letters on the 7th of October 2021 by COB, I am, still waiting for my letter and no one is able to escalate properly or help me in any other way, only thing that I can do is wait, it has now been 12 Business Days since the payment has cleared on Absa's side and the only update that I have is that the letter is with the Admin Manager waiting for sign off.
