Zomato - Instead of veg food zomato delivered non veg

I had ordered veg noodles with veg Manchurian and veg fried rice last night (*sep'**) on zomato. I am a pure vegetarian. They delivered the same but all were non-veg. I don't know how the non-veg tasted. I started having noodles but then a chicken piece came to the fork and I had doubt of such a thing. So I asked my friend who is non-vegetarian he told me it's a chicken piece. Then I opened all the packages I found all of them were non-veg. I raised a complaint through chat in zomato app. First, they refused to accept their mistake. But when I showed some pictures they apologies and said they can refund the amount. Because I never had non-veg ever before and neither I wanted to do. But they guys have made it. It's not a matter of refunding my money it's my religious beliefs and faith that is hurt.
I don't want this thing may happen to anyone else. So I want any action against them so that they can never even think about doing such a mistake again.
