2 Branches Not Assisting

I have been trying to open an Estate account and close my late mothers accounts with you but have not been successful. I went to SBSA Branch - Mall at Carnival on 16.11.2019, waited for more than hour to then speak to Ally (one of the consultants at the branch). He told me I cannot open an estate account because there are no Business controllers on available. He took my details and said he will forward my details to the relevant department. On Tuesday 19.11.2019 he called me and told me I need to go to K90 branch to open the account as he could not assist me. I then went to K90 Branch on 23.11.2019, spoke to Lindokuhle who also told me they could not assist me because the business bankers were not available. She also took down my details and copies of the required documents. She said she will forward my details to the relevant department and they will call me to come sign some documents. It is now Thursday 28.11.2019 and no one has contacted me with regards to closing my late mom's accounts and opening an estate account. Can someone assist me as this is really stressful on top of the trauma I am going through. I have been to 2 branches and no one seems to know how to assist me.
