Unpaid Pension fund

Good day. I'm writing with a broken heart & disappointment from Onwabile Sanlam I have been trying to claim for my late husband's pension fund for the last two year from 2020 April till to date I have not been assisted as when I try to contact them they tell me to call after a week.its been two years while waiting weeks after weeks, This money was supposed to help my kids pay school fees and other essentials but due to Sanlam staff negligence.Please assistant with the matter.This is affecting me emotionally,Financially & my kids as well as I am unemployed.My daughter had to drop off college due to no funds.I feel I am out of options.
