Vodacom funeral cover non payment.

My mother Nontobeko Magadu with DOB 1962-11-18, took out a funeral policy with Vodacom, with Policy no ***, for her late brother Welile Patrick Magadu. the premiums were up to date at the time of my uncle's passing which was on the 5th October 2021. My uncle died of unnatural causes. my mother submitted a claim with all required documents.... but to date, nothing has been paid to her. as the bread winner of the family I had to borrow money in order to bury my uncle with dignity he deserved. It has been a year since my uncles passing. It pains me to see my mother being sent from pillar to post, we visited several branches of Vodacom hoping to get help. I'm currently in debt due to Vodacom's failure to meet its contractual obligation. please assist me to hold Vodacom accountable.
