Expired food. - Consumer Complaint for Puregold - Head Office

I am very angry now. I went to puregold jr paeang marikina branch to have my groceries last October 4 2020 (sunday). I ate the yogurt . My tummy begins to crumple and i began to vomit. Then i check my yogurt is already expired Oct. 1, 2020. I will be attaching my receipt and the product. Is this the quality of service customer should received? The expiration date is october 1 and you allow those product to be on shelfs after it expires????!!!!! 4 days????!!!
