Shoprite Kagiso & Expired C***** yogurt

I went to SHOPRITE KAGISO and bought a C***** yogurt only after I've opened it I found that it had expired from 14/06/21 and today is 17/06/21. That puts our health in great danger and went back to the store I was made to wait and told the manager in charge that I'm on lunch and she said that I should go to the store and she needs to talk to the person responsible of the product and she will come to me with her store manager
