Sanlam sky don't deliver to their clients as they promised.

I opened a policy with sanlam sky where i registered my partner who ios the father iof my 23 yr old daughter sometime in March 2022 then my partner died of an accident in June then sanlam didn't pay my cash out, they said me and the deceased are not related because in my policy I did not register him as a partner I registered him as a cousin,due to their broker's negligence. Since today they haven't paid my claim they only gave me my premiums and told me that it was not even 6 months since the deceased have been covered with them, but when they make you sign the policy they say if a person died of accident emediate as he's been put on the system that particular person ois covered. I would like to ask for help to get my claim as I have been in debt for assisting with the funeral.
