Many requests for a paid up letter from Absa with no success.

I have been under debt review for 1 year due to the strain the pandemic has put on my finances and not being able to work etc., but have settled all my debt including my Absa credit card all in September 2022. All my other creditors have immediatly sent my paid up letters upon first request of them. Absa did not. I have emailed multiple times and made many calls to Absa and everytime the agent that answered promised I would recieve my paid up letter the same day. Up to date I have not received my paid up letter for my Absa credit card. It is preventing me from applying for clearance and ending my debt review journey and having my credit score reset. I do not know how I am going to get my paid up letter.
