Zomato — zomato don't refund my money

Address:

jaipur, Bathinda, Punjab, 151106

I've placed an order on Zomato but shopkeeper reject my order
But they didn't refund my money back. They are saying there is penalty charge. But I cancelled as Soon as possible. How they can say such words?
And penalty should be some amount of the order price. They are saying penalty charge is full of the amount of order.dn't refund my money back.
