I have booked tatkal ticket from ahmedabad to muzaffarpur, pnr no was not generated and in transaction history it was showing transaction id:[protected], i called irctc, they said your ticket is not booked, you will receive refund in 5-7 days.
I booked another ticket, thinking this ticket is not booked, but next day as chart prepared i got sms saying my 1 seat is confirmed and one is waitlist (Partial confirmation).
I filed tdr selecting reason as partial ticket confirm, now its showing cr registered from more than a week, when i will receive my refund.
