UIF funds

I worked 30 years for Nampak and I left on a early retirement. I was at home for a year and I received my retirement money, but they called me back after a year and asked me to casuals and I did so, for one year and three months. When I went back to them for my UIF they sent me home telling me I have to come back 2019. I went to them four times and they telling me now that I have to work another 3 months in order to receive my UIF. I have to stand there from 6 the morning and they open at 07:30. I am a pensioner and where do I find a job now ? I am over 6o years old already and they refuse to give me the UIF ! What do I do now ?
