Vodacom Mega Shake is a ****

I won a free 4 week course from Vodacom as daily Mega shake prize.

So I apparently won a free online course at Shaw Academy.To get the free course you have to supply your credit card details or you can't do the 4 weeks trial course. So it is not a free course.The Shaw Academy webisite doesn't look legit because I cant even register. What a disgrace for such a big corporate company like Vodacom to take me for a fool.I guess the entries into winning and Audi are also false hope huh ?
