Indian Railways — not refunding money

Address:

Howrah, West Bengal

Hello,
This is in regards to pnr number [protected]. Back in march 2017, i had booked three tickets travelling from varanasi kolkata
Ticket was for 9th march 2017.
Due to the trains running behind schedule for over 12 hours, i cancelled my reservation and requested for refund and raised a
Complain of tdr process prior to departure time. I have been chasing my refund since march 2017 and now 8 months later and
At least after 400 follow up phone calls, no update has been provided to me. I am still awaiting to receive my refund.
Previously i used to ring kolkata office and overtime they would advise me to ring them few days later and giving me a hard time.
In spite of having spoken to them at least 400 time they haven’t yet processed my return and keep making false promises.
Now they simply don’t answer my calls. The number which were given to me are [protected] and [protected] but it keeps ringing out.
