The order was placed on 12th Feb 2017 at 17:58. The order was of Rs. 673.
The guy from the restaurant requested me to wait for the deliver till 06:45 as it is far away from my home. I agreed to do so but no response was received till 18:45. I called the restaurant twice to know the status but the concerned personnel were just saying that "We will call you after knowing the status" which never turned up. I again called them to cancel my order as i need to leave my house and go out. They transferred the call to the manager and i asked him to cancel the order. He first told it is being delivered, then i told him that its not delivered and you please cancel it, he agreed to do so. At 19:15, i get a call from delivery boy saying that i am waiting outside of your house with delivery. I told him to take back as i have cancelled the order.

My issue is that when i agreed to give grace period of 15 mins, why it wasn't delivered and there was no call back in case of further late in delivery. Further, i have not received any cancellation confirmation of my order as i have paid with my credit card. I want my money refunded.
