I’m looking for my father Amos Sibiya

I’m looking for my father Amos Sibiya who’s originally from Swaziland around Manzini, I don’t know the exact location. My mother’s name is Sibongile Khambule. My father was working as a contractor worker in Richmond Chest Hospital at KZN around the year 1988-1989. He left when I was about a year and some few months and I never got to see him ever again. If there’s anyone who might know his whereabouts please assist me in finding him.
