Indian Railway Catering & Tourism Corporation [IRCTC] — tdr rejected

I have booked ticket from irctc app for my relative which pnr is [protected]. But on journey date train was late more than 3 hr. So i filed tdr and my relative travelled through bus. I personally received her at anand vihar bus terminal at 10 pm.
But i got mail from irctc that tdr is rejected with reason that passenger has travelled.
The mail i got from irctc as follows

"dear customer,

The tdr filed against pnr number [protected] with reason train late more than three hours and passenger not travelled. Has been repudiated by system as per the indian railways refund rules https://www.services.irctc.co.in/betaDoc/Amendments_RefundRules_2406.pdf

Reason for repudiation/rejection:, as per chart, passenger has travelled

Please note that the decision about the amount of refund or rejection of claim is taken by system as per extant refund rules of indian railways and not by irctc.

The status is also available online and found under tdr history.
