standard bank - deceased estates department

I have been sitting with a complaint for over 3 months that cannot be resolved, which at this stage I'm extremely frustrated. A HOMELOAN account and OTHER CREDIT accounts are still not closed with the deceased estates departments respectively and no one is calling me as the complainant or the my mother as the executor or even the attorneys handling the estate . I have attached conversations I have had with different standard bank Employees over the months and since then I have not been able to move forward , I cannot begin to express how this is starting to impacting the life of my mother and I the financial burden that standard bank is putting us under , the delays and ineffective and poor service we receiving are costing us money.

Can anyone advise why these accounts are not closed yet( for the ones that had credit life) And for the ones without how do we get to a point where we able to pay and close off these accounts ?

This estate late account is been open for over a year since we notified the bank with death notice.

I am extremely frustrated with this process and I’m asking for assistance please.
