Shoprite win R50000 competition utter "*******"

The Shoprite competition that says you can win R50 000 every hour everyday!!! I think its all lies, I have bought participating products, I have entered more than 10 times but nothing happens, here's the thing, I have tried via SMS.... It than shows me a message can not send to that number, I have tried in WhatsApp it that ask which you want to enter I say cash competition it says SMS your unique number, I do than comes back the same thing asking which would you like to enter, I have tried SMS it than says the code is invalid or has been used, I do not even get a notification saying that I have been entered or anything to confirm my entry.... What a waste of time, money , airtime and data... I do have proof of this Shoprite catch a wake up.... This is pathetic as people buy participating products with the hope to win, but how can one or will one ever win if you can't even enter....
