4th Initial cannot be added to my Absa profile

I have been a client of Absa for 17 years. I must be one of the few individuals in South Africa with 4 names. I have asked Absa Bank to add my 4th initial so that it appears in my bank statement but the bank has not been successful in doing so. This issue has been going on for almost a year.

There is a fund that is due to pay me since September last year. Everytime the Fund tries to pay me the bank verification fails because only 3 of my initials appear on Absa' side. On Friday 23 May I was at an Absa branch to try to get assistance and I was told that the FICA department has been contacted & unfortunately the system doesn't allow my 4th initial to be added. I am so disappointed & have no choice but to move & go to another bank.
