Indian Railways — passenger not travelled but refund not processed

For pnr no. [protected], travel date 24.09.2018 and train 18238, passengers didnt travel as train was late more than 8 hours. I filed the tdr and after 1.5 months it was informed that passengers travelled and my refund was not processed.

Is there no process to stop such corruption in indian railways. That tt might have allotted the berths to someone else and marked the passengers as travelled or may be at some other level corruption has taken place.

Kindly look into the matter so that such corrupt practices may be stopped.
