Address:

Zomato just delivered me rotten poisonous food and they are not responding when i ask to change the food. This food can cause death to person, but they are not showing any interest in what they have sold. And when i ask to take the food back and refund my money they are not listening, no complaint number is working, there is no response. I want the refund for same.
