Rejected Funeral claim

I would like to express my disappointment at Capitec Funeral Policy, I will never recommend you take as a policy that you take as the main policy need to bury your loved I made a claim on 7th of February 2025, the deceased is my cousin, the deceased living 2 siblings were contacted and the confirm that indeed our mothers were siblings through a father further more confirmed other family members relations to thier brother out of everyone I'm currently the only one who has a reject letter which was sent 4 days after the funeral, what ****es me more had they done a thorough back ground the would have seen I have claimed for my Aunt at Sanlam in 2022 but it was a natural death, now that it's unnatural and they don't want to pay they say my deceased mother and my deceased aunt are not siblings
