Hi @ntamho. Are you on the South African Slack channel? If not join here https://wpcapetown.co.za/2015/08/13/announcing-a-community-slack-channel/ There is a #localisation channel where we discuss translations of all South African languages.
I've also noticed Zulu has not been requested as a locale (I think). You can always be the first one! :)
Have a look at https://make.wordpress.org/polyglots/ for more info.
