Randfontein deceased uif claim

I have been going to Randfontein branch with no luck. The first person who assisted me told me that I must first bring the prove that shows that I'm related with my late sister and it can be the prove that shows that I was the beneficiary on one of her policies. I decided to contact my medical insurance since my niece she's one of my dependent and I also went to school to request financial statement because I'm paying my late sister's fees. My sister was working but under agent with no benefits. When I get back I was told that I don't have right docs, I went back to labour 5times now. They said they open 7:30 and cut the queuee 8:30. Before 2 they are done for the day
