Indian Railway Catering & Tourism Corporation [IRCTC] — Not getting refund from 4 months

Address:

Western Railways

I have booked a ticket on 21 february 2020 pnr-[protected] and filed a tdr because i didn't travel on that day because my ticket is in rac. After that they reject my tdr and the reason that they give me is that you have travelled on the ticket but i am not so i again mail irctc and attach a different date ticket from the same month as a proof that i didn't travel on that day and told them to reopen my case and the case is reopened and cr registered but it's almost 4 months but i didn't get my refund yet. I am angry and frustrated at the same time. Although i am attaching a ticket here as a proof.
Please resolve my issue as soon as possible.
