Zomato — my order got cancelled and my money is not refunded.

I ordered kfc from zomato on april 20th with order id#[protected] amount to rs.833 paid through my debit card.
I didnot received any calls from zomato and my ordered got cancelled with the reason that "not able to contact".
It is not my fault that zomato was not able to reach me. I shouldn't be charged for something i didnot receive.
I want my refund back.
