Zomato — sent rotten food

I placed an order for chicken biryani on zomato from swagath grand. They sent me the order which didn't have swagath grand packaging and the chicken pieces smelt rotten and bad. I was on chat with zomato customer service for 4 hours. They kept saying they will send another order and they have escalated the issue to another department and that will reach out to me. Even after sending multiples images of bad food and taste they just kept me waiting.
