Absa just stops accounts

Absa just decides to put accounts on hold. My private banker just has no clue whats going on. Got Funds in my accounts which I can’t access. Debit orders are to run abd will be dishonoured even though I have funds. I know numerous people who have been told by Absa that the bank has decided to ens the relationship with then. Even Absa legal department can’t give any answers. I need answers from Absa or will have to proceed legally
