D & D Deals

I accidentally purchased an expired food item on May *** 2020. I went back to the store on May *** 2020 to return the item to the store. The expired food is dated 2019. I went to the store to get a refund or an exchange since the food expiration date is long expired. The cashier refused to help so I asked to speak to a store manager, I was told there was no store manager or supervisor to speak to and they refused to reimburse or exchange the product despite proof of receipt with the date of purchase. The name of the store is D & D Deal's
