Severe illness claim

Hi I'm writing to Sanlam rergarding a severe illiness claim as I was diagnosed with cancer in April and started with the claim process in May after being discharged from the hospital. Sanlam asked for all the docs they needed to do investigation and I provided them with all those docs and gave them all my doctors contact details. I have never received any form of communication them. I'm the one who always call their call centre. I have sent them complains on emails and made call but still I dont get no update about my claim. The last email I sent was on the 16 of October and today is the 27th still there is no update no call no email nothing. My claims is taking to long to be concluded its been 6 months now I dont know what else I should do. Please help it looks like Living benefits needs to hire or train their staff on how to deals with claims of such nature.
