Disappointed

I don’t know how I have to begin to express my disappointment with the store that I love so much😫😫tell me how can a cake bought last week Wednesday to be expired now? It was a markdown cake with 30%off and, now we all coughing me and my mom… we noticed this after after eating the cake… my voice it’s even not clear.. I’m so disappointed and I’ve learn not to buy items that are markdown anymore!
