Swiggy — got non vegetarian instead of veg

Address:

Room No. 144, Ladies Hostel 4, University of Hyderabad, Hyderabad, Andhra Pradesh, 500046

I ordered veg munchurian from pissta house, lingampally nalaganda on april 8, 5.57 pm. Ordered from phone number [protected]. Email id [protected]@gmail.com. But i got chicken munchurian instead. I ate halfway, being a pure vegetarian and later realised that it is non veg. Got it confirmed by a friend. Had to throw everything away. I want the entire amount back, along with penalty.
I'm really frustrated and angry.
