Rotten food

I am not happy at with spar retail crossing on Hendrik Potgieter road ,I bought a cottage cheese there,on 11.07.2018, Nd yesterday when I was using it it was already expired,I went back Nd ask for another one but the lady Who helped me wanted to gv me attitude,but sh ended up telling me to go Nd Xchange,Nd when I got there by the fridge,they,most of cottage cheeses were expered,so it means they don't check on their stock, they sell rotten food! I was so so disappointed there I liked buying my groceries there!!
