Stinking packaging and off product inside

Hi yet again I have another complaint about your products !!!! My god I'm disgusted this time as we buy every month from your store and even our kids consume these products but this is just crossing all limits !!!! We have purchased two 6 packs of steri stumpie milkshake and guess wat these packs stink as if they are ten years old rotten mil****! Yet the expiry date says 11/4/2018 and 7/4/2018 ! I noticed this when I opened a pack to give to my two daughters my hands were even stinking so bad so I went and checked the milkshake and even that was stinking so bad! My daughter has advised she took it to school and drank and had to spit it out as it was off!!!! Now I have look through the packs cause two of the bubblegum favoured was consumed by my kids but I couldn't understand as to why both of them wasted it half way through!!!!! Ofcos who would consume anything off ! This is not the first second nor even third time in having an issue with checker hyper gateway store just few months ago I bought two packs of sweet potatoe pre packed which both packs were off and I was only given an apology and a stupid R100 voucher !!!! This time I'm going to put this report all over social media and HELLO PETER to make sure I am compensated for this is not only my money wasted but my children health as this could cause food poisoning !!!!! I will not take this laying down now cause the first time I ignored it and didn't report it then with the sweet potatoe I reported it and was told to report it sooner and got a sorry and R100 voucher and now we had just done shopping and this is absolutely unacceptable and I want my money back and I want to be compensated for my kids having to consume such products as well as my time being wasted!!!! A R100 voucher and an apology is not going to work this time cause we put out trust and health in these stores by purchasing from you guys and this the kind of products we are being sold! I cannot explain in words how disgusted me and my family are and this is the last time we will be shopping at checkers and we will be notifying as many people as we can about this !!!!! I have attached pictures of your worthless good!!!!
