ABSA just Blocks my account without notice or communication.

I am a client for 20 years. I financed multiple homes and vehicles with ABSA and never failed on repayment. On Friday the 27th of August 2021 I found out by coincidence that my Debit card was blocked. I phoned ABSA. No information was given. I was instructed to go to a branch to get clarification. I did that the next day. After waiting 40min in a queue I was told Senior council blocked my account due to instruction from the Seriff of the court. Surely I would give my client of 20 year a call or something to give him an opportunity to resolve this before just placing a hold on accounts. ABSA will never have me or my family as clients again.
