Zomato — order was not placed even though payment was successful.

H205 SUCASA WOOD RAJPUR KOLKATA, Kolkata, West Bengal, 700151

I had ordered food from chef alladin, garia, kolkata. My payment to zomato was successful through paytm showing paid 125.18 to zomato. But order was not placed. I contacted the restaurant and they verified that no order was placed. Order no.-[protected].
Right now i demand money refund.
I need to advise my friends and others to uninstall this app and instead use other better food apps until and unless i get a refund.
