Deceased Account

On the 18th of November I went to African Bank to claim money that my late mother have in their bank account, they referred me to the deceased estates court to obtain a letter of authority which I did, they told me that it will take 21 days to process, after I left I was called to come back as they received the required account statement which I did. They sent me back to the court to obtain another document with instruction that the money can be paid. The lady at the branch sent all the documents I received from the court as well as the estate account they required (non of the other banks I was dealing with asked for this type of account) with all the back and forth, I still have not received my mother's money. All the other banks paid within a week after I submitted the claim however dealing with african bank has been nothing short of a disappointment, in our time of need we still have not received the money mom left to assist with her funeral. even after the funeral there is still no money from african bank
