Unclaimed Funds from Goverment.

My name is John Mokoena a son of Solomon Mokoena who was a South African Police officer from 1981, he was shot on duty 1985 . he than stopped attending work due to injuries, those injuries affected his brain. as he was married to my mother no one was able to claim the funds from the government. As far riots between ANC and IFP which affected my grandmothers place in sebokeng, we moved to KZN. When I turn 18 years I went to Sebokeng for assistance since he was working there, but I was treated like I am stupid/ creazy. I went back again this year to Sebokeng HR offices they send me to GEPF offices in Johannesburg. I made means to get there and the person that was assisting me told me that she cant assist me, and anyway I might not find that anymore. they told me its impossible to trace my father because it was in the 80s, my question is how come they are not able to do so but home affair was able to trace that he was married to my mother by that time. I believe that my family borrowed my father to the state and my father never came back home the way he left us. His house was repossessed, his family never had a place to stay and moved to my mothers family house. Can someone assist me. I
