Indian Railway Catering & Tourism Corporation [IRCTC] — refund due to tdr

Address:

ASHA RANI CHAUDHURI, Behind Sabuj Sanga, Talbagicha South, Munger, Bihar, 721306

It was on 24/10/2019 i was traveling from kharagpur jn to njp jn via karmabhoomi express. The train was more than 3hours late and as per rules i filed a tdr against a family member of mine who couldn't travel due to the inconvenience. The tdr was rightly registered as i even call the irctc helpline to verify the same. And after getting into the train, i even informed the tc about the same and he marked it likewise. But now, irctc is mailing me by saying that the northern railways/frontier has repudiated our tdr as it was not claimed by the party. But i have every proof of the claim. The pnr along with the tdr complaint number as well as screenshots of the mail.
The pnr number is-[protected].
Tdr reference number-[protected].
I have complianed about the same to irctc innumerable times but the reply is always the same.
