According to a tipster and several reports from India, KitKat used Nexus 7 (2013) images when marketing the promotion, but then shipped the older tablet to winners.
When asked about this to Nestle, this is what they had to say : “We hear you’re unhappy. Winners got the Nexus7 tabs available in India in Sept (contest date). The new version launched only in Nov.”
Well, only if companies could make their marketing campaigns better!
