Indian Railway Catering & Tourism Corporation [IRCTC] — Refund - tdr

Address:

New Delhi, Delhi, 110014

I had booked two tickets on train no. 22482 for 14.06.2017 from delhi to jodhpur. The scheduled departure was 23:15. First it got delayed by 1 hour 15 minutes. At 12:40 there was an announcement that this train will leave by 2:30 am. Since we were two girls, we decided to ask the station master if there is any chance we can get our refund for the tickets as we can't wait till 2:30 am at night in delhi at a railway station that is fairly less crowded at night. The station master told us if the train is delayed by 3 hours refund is given but since it was booked online through irctc we have to cancel it online only and file tdr. Just to have a proof of the delay i got it in writing from the station master that the train will leave at 2:30 am.
At 1:00 am in the night, the irctc website was down, so i filed the tdr in the morning. The result: repudiated, reason: null.
I don't understand this, if the refund rules provide that refund is given in case the delay is more than 3 hours and i did tick mark the same option. Still the reason says null? I have written numerous emails to irctc about the same, attaching the stamped document by the station master, yet there is no response.
