Air Asia — Cabin crew sold me expired sandwich and I got food poisoned

AirAsia flight I5 747 from Del - Blr on 18-04-22:
I ordered veg sandwich and cabin crew sold me an expired sandwich which is tagged as "Not for sale" . Crew had ripped that tag and sold me the expired food, without seeing the ripped tag i consumed some portion of food and later when I brought this to crew they grabbed the sandwich cover so that I won't take any pictures of it and they were blaming this on the catering service. By consuming expired food I got food poisioned.

Later crew gave me feedback form to fill I am not sure if they had taken that form or disposed it.
