The way to treat a grieving spouse

The worst service ever from Rand Merchant Bank a part of FNB. My husband passed away and we need to close his account and transfer the money to the estate account for the executor to wrap up the estate. Documents were submitted on 18 January 2024. We were informed 30 days but they have a backlog so probably 60 days. The service is terrible. I am waiting now nearly 120 days. There is a log of weekly telephone calls , e-mails. They are rude when they are phoned. One is not allowed to get senior personnel to investigate. If you get a number or e-mail the senior staff is out of office. Never try to assist. This is an easy account to wrap up as there is no outstanding money from a bond. They are suppose to deal with people grieving a loss and all they do is trying to make the process as difficult as possible. Absolutely no effort to assist in doing their part in the long process of wrapping up an estate.
