Indian Railways — unethical behaviour

Reservation rail ticket:

Transaction id:[protected], ticket status:partially confirmed and wait-listed after chart prepared. Amount:1455/-

Request a refund: tdr entered for the wait-listed passengers only
Reason for tdr: party partially confirmed/waitlisted and wait listed passengers did not travel.
Tdr filing date:25/jan/2018 20:57:22 hrs
Cancellation id:[protected]
Tdr zone: south east central railway (Sb)

Result:
Tdr status:cr repudiate
Reason for tdr registration failed:invalid tdr timestmap:partial

Hence i loss an amount of 1455/- whole ticket.
1) why indian railways partially confirmed only a ticket and make suffering whole family like this?
2) why did not eligible to get wait-listed passengers refund, even train departured, even later on chart prepared for not allocated berths??
3) why indian railways couldn't reverse the amount to originate source if services not provided?
