Indian Railways — non refund of cancelled ticket

Address:

Mumbai City, Maharashtra

Sir,
I had booked a raliway ticket for my family members thru internet using my credit card. On the day of travel, the ticket was cancelled due to late running of trains. The travel was from Nagpur to Kalyan on 19th June. A TDR was prompltly filed and followed up a number of times. The matter remains pending. I am attaching a file print of the communication.
Request you to escalate and help me recover my dues from the railways.
I am giving the details below.
