Expired goods

I had a bad experience for the second time now with shoprite mabopane square, first time I bought a 5kg mixed potion chicken and when I reach home preparing the chicken noticed it was spoiled and had a foul smell while boiling decided to throw the whole package and did not go back for a refund or complain ,but now bought shoprite brand 30 eggs last week and now decided this morning to do breakfast ,found 17 eggs spoiled inside and had a bit of a foul smell again ,so disappointed and frustrated with this shop
