Sold expired goods

Bought 5 cartons of Litchi juice and on Christmas Day we opened one carton of juice.. to my surprise when my dad was drinking it I noticed the color of the juice was a bit darker and when I checked the date it had already expired on 17/12/2017.. like really?????? How does makro sell us expired goods? My dad had the runs since this morning and I know for a fact it’s that dark cloudy juice he drank from Makro. Am so disappointed really.
