Indian Railway Catering & Tourism Corporation [IRCTC] — Tdr repudiated

I have booked two tickets from Visakhapatnam to Chittranjan.
PNR are [protected] and [protected].
DOJ was 19th June'2022 Time 2:55 hrs . Due to agniveer riots we have cancelled our Journey as safety precautions. Many trains we delayed/diverted and cancelled that day. I tried to cancel the tickets 4 hrs before the scheduled departure of train from boarding station but unable to do from app. So contacted customer care and TDR was filed via mail.
I again have to book tickets from CURR_AVAL for Visakhapatnam to Shalimar and completed my journey details- PNR [protected], DOJ 19th June'2022 Time 15:30 hrs for the same passengers. From Howrah I have booked another ticket to Chittranjan for same passengers PNR [protected] and [protected] but the train was running late for more than 3 hrs and again have to filed tdr and took bus journey(I am having valid tickets).
My TDR for Visakhapatnam to Chittranjan been repudiate stating the reason that I have travelled in that train which is not correct. If I have travelled in that train then why I will again book ticket for the same route for same passengers. It is not possible that the same passengers are travelling in different train at same time. Please give my refund.
