EXTREMELY POOR SERVICE FROM SANLAM

My grandfather passed away in 2022 in September. Sanlam is attending to the deceased estate. I have tried numerous times to follow up on the estate as I am one of the heirs. All the heirs have completed and signed the "disposal instructions" as far back as the beginning of June 2023. To date hereof the estate have not been finalised. We dont get any feedback at all. Months and months on end with no word from Sanlam. I have tried following up with the correspondence address *** they were not able to assist as I could not provide them with my late grandfather's id number. Even though I had provided them with all the previous documentation from sanlam which needed to be signed by all heirs and which was done more than a year ago. The service is beyond poor to say the least. No feedback. No correspondence to the heirs. Nothing. At the rate they are attending to this estate the heirs will have passed on and it still wouldn't be finalised.
