Get rid of expired item on shelfs!!!!

Good day I went to pnp qualisave I bought one of their halaal sausages which was not even marked off today I tried to cook the sausages I didn't take me a minute I puked because as the sausage was cooking it had a bad smell and the sausage even changed color it's pink i am so disgusted my whole R60 down the drain because I bought a rotten sausage at pnp sies!!!! How do you keep rotten items on shelfs for customers to buy... Why not get rid of the rotten items I see some of the items are marked off as well I'm sure they want to still make money of rotten items what if it was my daughter who cooked that sausage and ate it and later get sick I really would've taken oppened a case for this I'm really not happy about this I don't think I will ever shop at pnp promenade ever again and please for other shoppers make sure when you buy meat or sausage from them it's rotten stuff they sell to customers!!!!!!!!
