Deceptive Labeling

My partner wanted to get an easy grab and go dinner before she headed out with friends. The sushi she brought home for me is labeled “vegan” not veg, veggie, vegetarian… “Vegan”. It’s not though. The sushi is made with the store’s seaweed salad, containing “skipjack, fish flakes..”. I’ve not intentionally consumed any earthlings for over a decade and can’t decide how to move forward. I reported this to corporate. They apologized and credited our card. I don’t want the apology and don’t want the money. I feel like the choice was taken from me. Food has been wasted, I’ve taken part in something morally wrong and it cannot be undone. Do I go to the store to see if they continue mislabeling the product. Then report it again, speak with store management, fix the label myself… all of this? Nothing?
