Indian Railways — refund for train cancellation

Address:

Kalpaka Theatre Road, Kozhikode, Kerala, 673007

I had booked a sleeper ticket to travel from calicut to udupi by train no 02197 (Cbe-jbp express) for 12aug 2019. (Pnr no.[protected] due to heavy rain and related problems train was cancelled upto mangalore junction from where udupi is just the next major station (Around 70 km). I was hoping that irctc would automatically refund the ticket fare. It didinot happen so far. Railway cannot expect me to travel by someother train without reservation upto mangalore junction and then bord train 02197 for the remaining travel which is only 70km. Since the train is not fully cancelled irctc has not refunded the money. I request you to make arrangement for refund.
