Why MTN and Vodacom fail to make their own unique promotions to their customers than Copy and Paste from Cell C



Cell C was the first company to launch this 2gb free every 12 months promotion .

Vodacom followed with Copy and Paste just charging the Color to Red and this night crazy night shift thing.

Now is MTN (Empty-N) is also doing Copy and Paste, which color did they put is it Yellow?
