Pledge on my account remains unresolved

A pledge was put into my account 4 weeks ago. There is no reason notes with the pledge, and after 20 calls to everything from ***** to digital banking 6 visits to branches everyone just throws up there hands. I have visited SARS because I was told this is SARS fault but they have even issued me with a certification of good standing. Every single call has ended with the person telling me they will call me back, yet nothing is done. This is my money I deserve a answer and I should have official communication why this has happened.
