Taking advantage of the dead

My grandfather past away in April and my grandfather had a trust/ will with ABSA. They have given our family the run around since then and their consultants has been rude, disrespectful and utterly unprofessional. The will has still not been read, the consultant told my Uncle which has power of attorney on my grandfathers accounts that they are too busy the will has been send to Kuruman and in the meantime the account of my grandfather is drawing interest, which my uncle will just have to pay. ABSA is taking advantage of a dead person and in a time of grief making the situation so much worse on the family.
