Swiggy - Non veg food delivered which create hatred

I ordered a Dal makhani by swiggy on **.**.**** {Order id: ***********} as I & my family are pure vegetarians. We are Marwari by caste but they delivered a Chicken dish. When we seat for dinner we open the box we found it non-veg item. As my parents are old & very much touch to religions they are in shock. Even my Mother after seeing the same started vomiting & still from the time she didn't have any food. Its created a hatred in her. I think I have to consult a doctor for her. I want justice how can such an irresponsible company touch our religions. When I complain at swiggy they are not sorry at all just saying sir we will send you a cash voucher for the same, use it in the future order. How can they think that we will order again in future? I need justice for my parents who even don't allow egg or mushroom at home their religions are touched.
