Cambridge filthy

I bought 3packs of rainbow chicken at cambride foods nelspruit branch 21/05/2019....nd when i opened 2 of the 3 packs it was rotten. The smell alone it was as if someone died. I had to throw it away and cook something else. The smell at the store at the butchery was also off, the meat fridge looked like it had not been cleaned in months. Quite different and dirty from what it was months ago.
