Absa's incompetence, disrespect and never ending process in claiming for a will

My Dad older brother passed and left a will to my father. As we all believe that wills should make things easier on the deceased assets for the people left behind. Unfortunately this hasn't been the case with Absa as my father is being sent from pillar to post(after submitting all the docs required), and incurring costs while at it, i.e telephone cost, data and logistics etc, i don't even want to add the stress that we all now feeling as his family. To make matters worse communication is not good from Absa side, when my father reaches out he is constantly being told one thing after another or the gentleman from Absa hanged up the phone on him. What a lesson us as a family have learnt from this experience and i want to make sure that unlike us, everyone avoid this company and doesn't have to go through the same treatment. My sister was thinking of having a will with Absa but after this she will not even dare. Such incompetence and not only disrespect to their client but to an elder.
