Zomato — zomato cancellation policy issue

I have provided my complete house address and just my contact no was not reachable, my order has been cancelled. Zomato is now refusing to refund the payment for the order which was never delivered to me. I could see the live tracking system that delivery guy was quite far even 2 kms away from my location and never attempted delivery and when i tried calling him, he was not reachable. He deliberately cancelled this order as it was already prepaid. How could be my fault, moreover, i haven't received what i paid for.
I also forwarded a mail for the same issue.
