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 6812300890086, 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
