Ixigo and Airindia express - No Show Refund not received

I had booked a ticket vis ixigo app PNR Y**LFQ, Susheel Kumar Bhandari.
I had paid extra for full refund but due to personal circumstances I did not board the flight and I had called the airlines and took a no show refund but instead of refunding the whole tax amount they had only refunded ***/- to the booking agent i.e ixigo but then ixigo is not refunding the amount and is saying they will deduct cancellation charges (I had paid extra for cancellation while buying the ticket), they will deduct the convenience fees (it's paid seperately while booking) and discount given at the time of booking (that was deducted on the base fare not on the taxes). Ixigo is cheating with PPL it is our right to get the tax collected if we don't fly. Please help getting the rightful refund.

Thank you
