Spar

I think Spar is trying to kill us, earlier on today me and my girl went for a little shopping amongst the items we bought we also bought 2x450g danup boost berry flavor. We got home started consuming the yogurt and we both tasted a sour taste we than decided to go back and buy the same danup at a different outlet which is Picknpay dan we consumed it in-store, that's when we realized that the 1 from Spar is defective, we brought all 3 shakes to Spar as to get an explanation as to why those two from Spar were white in color and dan from picknpay was berrish(red) in color. We got a very stupid response from the team stating that theirs is 3in1 but none to answer as to why the taste and color differ, the one from Spar is white and bitter(not expired according to dates on the container) and the one from Picknpay is of the quality we know off!!! 6 children have been killed due to food poisoning earlier this week in Soweto!!! I don't want this to be the case as I'm fearing for my life as what I have consumed.
