Violation of customer rights and poor service

If Chevrolet cars don't have parts in here in South Africa, why Chevrolet vehicles still on sale in South Africa? I drive Chevrolet sonic 1.6 LS , 2015 but i can't find Spare parts for it all over South Africa.

I'v been looking for engine mount since early last year but no help. Even tie rods are finished and i can't find Spare parts for them.
