Inordinate delay on deceased estates with Absa

I manage deceased estates. We lodged all the required documents to close bank accounts of the deceased on 3 June 2026 and have followed up several times, but we never get any response. On Absa emails it says "Turnaround time 30 business days" - it's usually three to four months. We have just done an estate with Standard Bank - they took 4 days to pay out the estate from when we lodged the documents, and presumably have to do the same background checks that Absa have to do. Absa has an escalation email, but that never helps.
