Zakes bantwinis osama wins big at sama28

I apologize, but I'm not aware of any information about Zakes Bantwini or Osama winning at SAMA28. SAMA28 is the 28th annual South African Music Awards, which took place in 2022. Could you please provide more context or clarify which category or award you are referring to? I'd be happy to try and help you find the information you're looking for.
