Indian Railway Catering & Tourism Corporation [IRCTC] — Cancelled ticket refund

Address:	831011
Website:	www.irctc.co.in

I have cancelled the following ticket two weeks back, but the refund has not yet been credited to my bank a/c.
PNR: [protected]
Date Cancelled: 05-Mar-2017
Transaction ID: [protected]
Settlement ID: [protected] dated 10-Mar-2017
Refund Amt: Rs 2320

IRCTC gives a very nonchalant reply that they have already processed and the refund should take 2 - 3 days (from 10 Mar 17), though already ten days have passed without result. At my bank they have no clue and just ask me to wait.
