Dont sell Old Stuff

I bought my son a PJ Masks Choc dip on Tuesday 2nd May at 475 Imam Haron Rd, Lansdowne. The Saturday we opened it, it reeked of old metal, tasted horrible, and my son got sick.The BB date was 1/April/2025..now i know you going to say " why didnt you check the BB Date"..but why would you even sell it to the Public... Horrific
