Prescription letter

I recently discovered that Absa Credit Card placed a judgment on my Credit Record. This for a Credit Card I have no record of, nor do I know how the Credit Card was issued on my name. I contacted the Collections Department who referred me to ***, to get more information. Absa legal responded, "Please note that your Absa Credit Card is prescribed, and a request for prescription letter was sent to our admin department".

I have not received any communication from them since they sent the email on 31 March 2022. I have emailed them multiple times, but have not received any communication. I again contacted the Collections Department and they assured me that it would take 3-5 working days. Today is 12 working days, without any feedback. I need the prescription letter, to have the judgment removed from my Credit Record.
