Nestle Kit Kat Competition Entry Rules Unfair.

Over the weekend I was lured into buying a chocolate KitKat bar, as Nestle are currently running a competition to win R3.5M in prizes However after buying the product, I noticed that the small print at the back states "the competition is open to all legal South African Citizens ONLY" I find this rule deplorable and even somewhat Xenophobic. Also it is tantamount to false advertising by attracting ANY consumer into buying their product with a chance to win and then in the small print limiting who can and who cannot enter. Perhaps Nestle would like to respond with their reasons for limiting entrants.
