Address: Kamrup Metropolitan, Assam, 781001

I booked retiring room on 18 june for my friends through irctc website. Pnr [protected]. Rr referance no - ghyrr464133, transaction id - [protected]. But my friends could not take the train because the train was canceled from railway authority for landslides problem at lmg - scl section. So in such case i could not check in retiring room guwahati, i got the full refund of train ticket but my retiring room refund is still pending and yet to get back in my account. If i had not check in on 18 june in retiring room owing to train cancel than i should get the full refund of retiring room but its still pending from your side. I contact irctc, they registered case with ticket id: "irctc 3679788 and irctc 3668197" and forwarded the matter to chief commercial manager (Refund) n. F. Railway, hqs - maligaon, guwahati via letter no - 2016/irctc/ertd/retiring room refund/ (412)/0344, dated 14.7.2016. Copy of that is attached.
