Coldcase Tracing Claim Payout

In September 2019 my father received a from Cold case about his claim to submit the required documents which I did. When I made follow ups the said they are still busy with the claim until they told me to submit again in August 2020. From that time till now I have been making follow-ups with no response. How long will it take them to process or pay out the claim or is it a **** We need the progress/answers in this regard Ref number ***
