Absa Deceased Estate department is not attending to us

MY father passed away on the 27 September 2020 and left a will with Absa bank. Meaning Abas is the estate executer. We went in with my fathers widow to diepsloot absa and were advised our very unique situation advising of the magnitude of the estate the large number of dependents and how we need their lawyers to start the process for about 6 vehicles bond repayments life covers we cannot access and recently a R15900 water bill from Johannesburg water of which we cannot handle without a letter of authority which is what absa should be doing on our behalf. Its been over a month and we still have not been contacted or had someone read the will. I last spoke to the department on monday 2 November. a consultant asked for 48 hours and never got back to me since. Our situation has now gotten extremely desperate these delays will end up leaving the estate insolvent as all his creditors are calling. Absa has done nothing to date very frustrating and disappointing and frustrating. Poor poor service
