Expired food- Health Hazard

I bought frozen butter fish yesterday on the 11th of May 2026 around 17:20, when i got home around 18:30, i fried the fish only to find out that they are spoiled after taking a bit. They had a dark brown color. When i checked the expiry date they expired a month ago.

I am truly disappointed in this store... Thier expiry dates are always so close
