Expired Yoghurt

I went to Shoprite Usave in Mooi street if that's the street, on the 20/12/18 mainly to withdraw cash but then decided to buy some yoghurt and C***** Duo juice. Today 23/12/18 when I open the yoghurt to eat it,am surprised by its watery texture,when I look for the expiry date only to realize that it's 22/09/18..*** is this really,is this how Shoprite treat the poor and sell them expired goods whilst providing the worst service ever in the process?Definitely going to escalate this to the relevant Ombudsmen
