EaseMyTrip.com — Refund of my cancelled booking

I had booked a vistara flight from easemytrip...the total cost of journey is 58000 INR and easemytrip is charging me 46000INR as cancellation charges...when asked why such a big amount they just say it's the airline charges... wherein the airline cancellation charge is 18900INR for entire trip...the airline has put in a vendor remark for easemytrip regarding the same but easemytrip is denying that any remark like this is there...i do have a screenshot of the remark... easemytrip clearly reads it wrong and lies to us...all the staff whom we have spoken to are rude and lack basic manners to talk to their customer...we told vistara to cancel the booking and they did so and said remaining amount has to be collected from easemytrip...when we contacted easemytrip they said go to our app and cancel the flight...we were telling them the app says refund of only 12000INR so they said if the airline is giving you more refund then we will return you that also but after 2 days we saw that only 12000INR were returned to us saying that airline deducted the rest amount which easemytrip is clearly lying about...our 25000INR is stuck with easemytrip and they say they have escalated our case to airline regarding refund but no callback from them
