Swiggy - Received chicken momos instead of veg

This is to inform you that we ordered chicken and vegetarian momos. My mom is vegetarian. So for her we ordered veg momos. This is the first time we ordered momos. As my mom is diabetic and needs to take her insulin injection and her other medicines on time so she quickly opened her veg momos box and ate one momo out if excitement and then she threw it saying it tastes different. So I and my brother took a bite of other momos. It was actually chicken momos. She even threw up twice because she feels so disgusting. We are brahmins but I and my brother eats non veg because we have been studying in different places.
This is disheartening and shameful that when I ordered veg momos still we received chicken momos. I paid Rs*** and got this. Customer support agent constantly kept saying we are unable to compensate and can only provide Rs.**.
