Death claim taking forever

Good day, I'm beyond frustrated with sentinel services. We have a death claim with them since April 2023 of our kate mother ID ***, our claim benefit was handed to PFA last year (i do understand why it has taken this long) but we won the case last year November the 15th & we were sent emails to send our bank proof of accounts, which we did on the 28th of November 2023 In January 2025 i did a follow up of the claim & i was told the ddnt receive our documents then we sent them again.. The problem with them we must do the follow up and they were requesting the documentations 1 by 1, February the 12 2025 we sent all the required documents to this date we haven't gotten the payments & there is no communication again. I wanted to ask how long does the process of payment take when they have all the documentation.. I have a 2 siblings , 1 nsfas hasn't fundend him & the other one hs special needs
