False advertising

False Advertising on a shelf where they advertised tha if you buy 2units of Oreo 133g you stand abchance to win XBox Series Xs. After buying what is advertised I went through the fineprint, Competition was for 1st to 31st October 2021. This is wrong and I am not happy at all about this. I bought for over R3000. I wasn't going to buy 2 Oreos if it wasnt for my son who wanted to enter this competition.
