Adding people on Policy

I tried calling Sanlam with no success, My aunt took out a funeral policy in 2021 and added my brother and I, she has no relationship with us, I called Sanlam to inform them that I want to be removed from this Policy, after a huge fight I was successfully removed from the policy. Now my aunt Id number *** they are stating that my brother is wanted by gangsters and they want to shoot him (that is all lies) she added my brother because his on drugs and wants to claim, Today I was informed that people came to my aunts house looking for my brother with guns and they want to kill him because he "****** " someone and that is all lies made up by the policy holder whose my aunt.

I want Sanlam to remove my brother from my aunts policy as she has no relationship with my brother my brothers id number is ***. Kindly contact me as this is a matter of urgency ***
