Jet Airways — appeal to get refund against pnr no:rnokhx

I have purchased a air ticket of Jet airways having journey date on coming[protected] from BOM - CCU. Jet airways already direct me over help line phone to contact irctc where from I purchased the ticket through my personal ID, to get the refund value of Rs.7798/- as the flight PNR: RNOKHX is cancelled by jet airways. irctc didn't give me any positive response still today. My Purchased Ticket details is as follows:-

PNR NO: RNOKHX, FLIGHT NO: Jet Airways India 9W-617, D.O.J : 05/07/2019

S.No Passenger Status Ticket number Policy Number
1. Mr. BIVAS KUMAR PAUL Delivered[protected] ID00051089
2. Mr. KASHI NATH PAUL Delivered[protected] ID00051090

Kindly check my PNR status and refund the purchased amount directly to my bank a/c, where from the amount was debited

An early action regarding the same will be highly solicited

With thanks & regards
