Pick 'n Pay selling non fresh meat

Pick 'n Pay Sanctuary mall in somerset west, sold us meat (Ribs)that was past it's best before date and they hid the dates on all packs with a price sticker... I contacted customer care through various platforms and have not been assisted. I took pictures and send them but still nothing, when I went back to the store they made me wait 20min before I could speak to anyone so I left...
