Damaged goods

I've bought food at Middleburg Shoprite and digested after a long painful stomach thought I must check what I've eaten I quickly checked expiry date on that foods just find out that is expired. I was not gonna report this but is annoying cause is not the first time this happens to me at first I thought I didn't want to expose them but now I realize is not about exposing a company is about saving my life and millions lives that shop at Shoprite... I'm highly disappointed as a customer
