Indian Railway Catering & Tourism Corporation [IRCTC] — tdr status showing cr registered but refund amount not received

I have booked a ticket from RJY
to KCG on 18th Sep,
2018 and Date of Journey was 16 Jan, 2019.
For reason passenger has not traveled, I filled the TDR
for the same in IRCTC against my ticket and the
status was turned to CR Registered, but the
amount was not refunded yet.
I am not sure what else I might be missing to
get amount refunded. Please let me know what I
can do further or else you can send sms to mob no : [protected] or
