Terrible service from deceased estate department.

I would give them a 0, if possible. The deceased estate dept is absolutely useless. Very little, if any, response. A credit life claim which I have been battling to claim, pertaining to my late husband's estate has not been paid over into the estate account up to today. However, I have recently received a 'claim' against the estate of said amount! The executor requested funds in the cheque account of the deceased to be transferred to the estate account on 22 March 2022. We have had NO response to this request. I want the estate concluded, however FNB'S non / unsatisfactory response has been dragging on for the past 2 years, and still is.
