Expired goods

I bought Almond, Cocoa & coconut bar mutlipack at Mthatha Mall on 11 January 2024 Saturday, I took one the same day without checking expiry date and today when I took another one I notice the expiry date is 29 December 2024, imagine buying something and eat it only to find out that it expired long time, I am so disappointed and angry at the same time because I don't know what the 2 bars I ate can cause health wise
