Very angry

I dnt know what to do any more regarding this issues as a consumer. I have a problem with Luvuyo Burial Society has been promising to payout the cover and policy is up to date and I have submitted all the required documents. My dad passed away in March 2022 but Luvuyo Burial Society keeps on saying the claim is due for payment since June. They no longer respond to emails and they are very rude when speaking over the phone. I would appreciate your assistance
