Zomato — food did not deliver and no update on refund of paid amount

Address:

Bangalore, Karnataka, 566016

I ordered pizza from dominos pizza using zomato app. The message i got was, the food will be delivered in 30 minutes. There was no updates for 2 hours while i was waiting for the food. After 2 hours i got a call from dominos pizza that the food can not be delivered to my location as it is out of delivery service area and they cancelled the order. As i paid the amount by zomato mobile app using paytm i did not get any money back. I need support in this issue. There is no way to contact zomato! No one reached out to me from zomato on cancelling my order or refunding my money. Need some assistance in this issue.
