Indospirit, 110020

I placed an order with Zomato for Rs 220 and cancelled it within seconds, my phone got stuck, i received a message that Zomato will not refund my money as the food has been prepated, I called the restaurnat directly they said they have not prepared anything as the order was cancelled within seconds and at the same time they have received mail from Zomato saying that the customer will be refunded the Rs 220 as the order was cancelled within 1 minute of order placing. This is theft i want my money back
