I want my remaining money

sanlam sky:death claim . i logded a death claim on the 30th of Oct 2023, and i was sent from pillar to post even though i submitted all the documents. i was informed on thursday 2November 2023 that due to the type of death i have to submit an inquest report. i was then paid on friday the 3rd November 2023 late. When i check the payment it was paid by the wrong names of the decesead. meaning a member who is still alive was paid . I got a low or less payment because the policy was not checked by sanlam. i have not yet received the remaining amount. instead of R38 000 , R25 000 was paid. If it roles were reversed i would have to pay it back. The deceased is Teboho Makoko,not Teboho Dishea(who is still alive)
