Zomato — non refunding of money my order id [protected]

On july 28th, placed an order through zomato app. For a few items with cream centre in coimbatore. One of the items was channa bhatura. Cream centre called me up to say that i should place a separate order for bhatura as channa bhatura does not include bhatura!! I felt that this ridiculous and cancelled the order. But before cancelling i asked zomato re. Cancellation charges. Neither call centre nor the chat person could provide any clarity.
Now they are not refunding the sum of rs.1040.

My emails do not solicit proper responses and they have stopped replying my mails in the last 18 days.
They are not even refunding gst (As items were not billed), packing charges (As items were not packed) and delivery charges (As items were not delivered)
