Zomato — amount not refunded, they are cheating

Address:

Hyderabad, Hyderabad, Telangana, 500038

I have ordered food from krithunga ameerpet, Hyderabad, we are waiting for food, my mobile also working fine, but i didn't received any call from the delivery boy, when i chat with zomato customer care through mail, they given below reply,
"We have checked with the delivery person for your order ID [protected] and got to know that he tried to call you at the time of delivery but you didn't respond to calls and in this case, the order was declined due to a reason o[censored]ser unresponsive. Since the food was already dispatched, the cancellation charge equal to the order amount will be levied.
Hence, we are unable to refund for the same"

As i didn't get any call from delivery boy and also am in a pick up point waiting for food and without any intemation they canceled my order and money also not refunded within time (And within 1hour how can the food will waste as they are providing a cheap quality food it seems so in that case only food will get waste) And i have ordered end number of times in zomato and this is the first time where am facing this issue and hope you understand from where the problem is, so please refund my amount within 24 hours,
