Swiggy — Food poisoned for 3 of my friends

I have ordered 3 shawarma's from my friends phone and they delivered it finely without any issue. Then we taken and ate .On the next day everyone got sicked . we went to the hospital. After all the tests they said to us is you got stomach infection due to that food. I have hospital bills and reports. And my friends are admitted in the hospital .

Who will take responsibility for this? Who will pay for it? We need justice. Otherwise I will raise a complaint against swiggy
