Expired Food

I went to a Shoprite Store in AlexMall and bought some stuff I’m gonna need including Melrose for my baby. I decided to try it and it had this weird taste but I thought it’s probably because it’s been a while without eating it, until my stomach started feeling weird and I had a runny tummy. I then decided to look for the expiry date only to find out it expired 31/10/2025 and I had just bought it today 26/01/2026. I am utterly devastated and hoping I haven’t consumed food poisoning. I need a full refund and medical treatment from them.
