Struggle

My mother passed on in November 2023, since then I tried to cancel her bank accounts, first they said I need to wait for the Letter from the Master, so I waited, when I received the letter, I send all the necessary documents to FNB, the Manager at her branch advise me to mail everything to the decease-accounts @ fnb, still nothing I asked help from someone I know at the bank, nothing and still I'm waiting, there is no process that I can follow no number to follow up or no email to confirm that they received the request and that they are working on it. I can't believe that is such a struggle, I want to get this done now to put it behind me and get closer.
