SACCAWU Policy Claims

My brother left me and my brother money in a policy to claim after his passing. It’s been over a year and SACCAWU won’t release the money. They keep saying it’s under investigation which I don’t understand because what are you investigating, there is proof that he left it to us and he has no other beneficiaries. They also not answering any emails or giving any feedback on where they are with these investigations. Another thing is that “board” that’s doing these investigations has to agree and find me and my brother worthy of the money, but I don’t get this because my brother worked all his life to leave us this money. When we called they said they are short staffed and dealing with hundreds of claims. I’m concerned and worried about people who don’t have the resources to fight for their money. It’s really been frustrating.
