Sanlam Life Policy very disappointing

I lost my older sister in 2017 who was the one & only breadwinner after my father's passing & my mother retiring. I lodged a death claim in a month after her passing with Sanlam for my sister who had 3 children & after 3 years of being sent from pillar to post & completing numerous documents & calling every month I'm told the claim is still being investigated. The whole of 2017 we were sent to all doctors & made to get doctors to complete questionnaires & 1 doctor had to be paid from our pockets, we returned the numerous questionnaires & each time I followed up with a call using my own airtime I was told the claim is being processed. 2018 last year I was requested banking details for my mother & my sisters children & I had hope that the claim is being finalised but till today nothing! I have just checked the numerous emails to Sanlam & on all these hundred emails I'm screaming & only to be rep**** by a no-reply email saying the claim is still being investigated. I have been dealing with Loraine Marais, Ina Blomerus aswell as everyone else & I'm pretty sure all consultants know me by now from all the numerous phone calls & emails to Sanlam. The children are in school & I am trying so hard to make ends meet & it isnso heavy on me as I am now the only breadwinner at such a young age taking care of all my family members. Sanlam keeps dragging this claim& it is with sadness that the person who thought they made the best decision by taking the Sanlam life policy where she thought her family will be looked after when no more is not here to see this. Sanlam cleary is interested in taking premiums everymonth but does not care what happens to the family after a person passes away. I made another follow up last week & on Wednesday the 24th of July & was told by a manager that the claims is now with forensics & they don't know how long this will take however she will call me the following day but till today no phone call or whatsoever. Old woulds which haven't healed are now opened by an insurer which tries by all means to repudiate claims. When we take up policies how come we are never told that all of this will happen? I am very dissapointed by Sanlam, the family is suffering and they seem to care less. Can I please have someone intervene and help here please!!!
