I have ordered food in zomato today afternoon then i went to a meeting. I thought food was delivered with security officer but i was shocked the food not delivered and i have checked with the app it said like food not delivered and also i have received no refund
I called the delivery guy he said the food is returned to the restaurant and i called the restaurant they said please speak with the zomato we can't do anything again i called the delivery guy he said come to restaurant i will ask about the food. When i went to restaurant they said we will receive 50% amount we can't provide you the food ask the zomato customer
Then chated with zomato customer care he replied we can't give refund so i asked for refund policy he said i can find while ordering the food.
