Swiggy — Swiggy delivered bad, expired, rotten food

Today we ordered Daal Makhani using swiggy, we looked at ratings of 4 star of the restaurant named "Srinidhi Veg". The food was delivered, as soon we opened the packages they were clearly smelling with foul smell of expired/gone bad daal makhani.
We called up restaurant and they indirectly accepted it was old left over food delivered. When asked for my money they said to contact swiggy.
When i am trying to contact swiggy only options are CHAT and there is no option for bad food.
I cannot even find the helpline number to call and inform them.
This is so pathetic customer service, where you are giving a restaurant as 4+ star and that resturant is delivering bad food to play with peoples health.
