Indian Railway Catering & Tourism Corporation [IRCTC] — Refund of tatkal wl ticket

Address:

673593

I booked a ticket ([protected]) Transaction ID [protected] from CLT to TVC on[protected] and the status was CKWL.

The amount deducted from my account was 792 Rs and ticket cost was 770 Rs., and the ticket didn't get confirmed after chart preparation, but i received a mail saying that 650 Rs.will be refunded. But nowhere in indian railway and irctc sites its mentioned that 120 Rs. will be deducted if ticket gets auto cancelled.
120 Rs is deducted on base of what??? You are already taken service charge, and i didnt get any ticket. Still u are deducting 120 rupees for a ticket, is something like robbery !!!. People didn't except this from Indian railway and its subsidiary organization IRCTC
