ABSA deceased estate and complaints resolution departments

I often deal with estates in my capacity as an attorney and agent of the executor. I am under the impression that Absa is making a habit of delaying the payment of funds held by them on behalf of the deceased. I am able to provide proof that this is the case with many deceased estates. Repeated emails to their complaints resolution email address proves to be fruitless, they just do not react!! I experience this to be extremely poor service and would like to know how Absa and their deceased estate department regard the situation of widows in an estate. Absa owes the public a motivated explanation which goes beyond their usual superficial apologies not being followed up by any action. In the current case the deceased passed away during July 2021. We need transparency from Absa.
