Airindia — Flight ticket

Website:

Airindia

I booked my flight in airindia through paytm from jamnagar to hydrabad for 7th of March
But due to flight timing was changed by airlines so I ask airlines to cancelled my ticket and process my refund so they told me u have to contact your travel agent that means paytm regarding refund issue.
Now its been more than 14 days I havnt received my refund yet and not even cancelation massage of my ticket.
I called paytm about this so they told me airlines not refunding my money when airlines refund your money to us than we refund your money please tell Airindia airlines to refund my money
I booked 2 tickets.
