Swiggy — cockroach in my food

Address:

Lb nagar , Hyderabad, 500035

I have ordered a biryani from nakshatra grand restaurant via swiggy on 23-02-19. It had a cockroach in it and i complained it to swiggy. They have promised me to refund my amount through voucher which they did not. When i asked them again on 28-02-19 they say they cannot do anything about it now. Please take action on this people for providing such bad quality food and endangering my life with cockroaches.
