Dis-Chem FOOD POISING

Earlier today I went in to a Dis-Chem in Boksburg bought a Steri stumpie Chocolate , I took a sip and then found it to be rotten I puked my lungs out from the chunks and and smell of rotten milk , I went back to show them they sold me a rotten steri stumpi it was past expiration date even showed on there system i was told but was never removed . I received a refund of the money not the full sum because apparently the chips that they said were free was not free on top of everything not once did they apologize or show concern for the fact that they made me sick to my stomach they played with the rotten steri stumpi teasing each other finding this very funny the whole day my stomachs been a mess constantly nauseous and wanting to throw up .
