Sanlam - Waiting for over 2 months for payout

My father had an account with Sanlam whereby the amount would be paid out once he passed away and equally divided between my sister and myself.

My father passed away 30 August 2022. We handed in all relevant documentation to the Sanlam representative on 01 September 2022. The person said all is in order. We waited a month with no feedback or contact and from month 2 contacted the person weekly about the payout with remarks "They haven't come back requesting more information so all should be okay, we just need to be patient and wait for the payout"

How can it take almost 3 months for an account to be verified that the person died and that the 2 people on the profile has correct bank accounts to pay out.
