Swiggy — provided a rotten food and customer care doesn't give a damn about it

Address:

Chennai, Tamil Nadu

I ordered 3 dhal and coconut polis from Louie sweets and snacks at Chennai. They gave a rotten and old food which tasted sour and bitter. When I escalated this problem with the customer care they were not ready to answer properly. I am a regular person who uses swiggy and a superuser too. Past few days customer care executives are very impolite in their order.
