The traumer and up&down that StandardBank has caused me

My name is Amanda i've been claiming my late mother's money that was on her StandardBank account since May but no luck cz i was told that the account was closed long time ago, funny coz i did get the statement from the branch but suddenly the account was closed and they don't know where the money is since May this year until i recently found out that the money was transferred to banks account (commission unclaimed balance) until someone comes forward to claim it but all along they never told us that, all they could tell us is that the account was closed, on the 18th November 2022 i did resent all the documents for the claim to their deceased department but i never received any feedback whether they received them or not and I'm not prepared to wait any longer than I've waited already, they must just move the Money from their account and put it the account given, StandardBank is ***** that's all i can say, ********, fancy ********
