Indian Railway Catering & Tourism Corporation [IRCTC] — about refund issue

I have booked ticket on 13-8-18 for the journey on 20-8-18 from KSR bangalore to KBPR (kabaka puttur), PNR NO; [protected], and return ticket on 23-8-18, PNR NO; [protected].
Due to heavy landslides near yedakumer, shiradi ghat and other locations the train has stopped running on that days, i have contacted railway customer care also there was no proper information or response from them. so kindly please refund the amount as soon possible.

Thank you
