who is the lady from the nestum adverts?

who is this lady in the nestum adverts? she is presumable coloured, and has a longish face with shoulder length curly hair.
she is also in the sabc 3 continuity adverts. (the one with the desk fan blowing leaves at her face. there is an alternate version were her hair is blown onto her face) i also think that she was in a shwepps advert as well some time back.
