Indian Railway Catering & Tourism Corporation [IRCTC] — insufficient refunds

Hi,

I have cancelled a ticket with pnr number :[protected]
I checked the current status
Which is still in waiting list (4 members rqwl4 to rqwl7)
So i have cancelled on 17 march
I have paid 1900 for the 4 tickets (475 each) while booking,

The railway e-ticket refund policy says when
We cancel waiting list ticket before 48 hours,
We will be charged rs 60 for each person
And for the confirmed ticket it will be rs 120 per person

As i have cancelled the ticket which was in waiting list i should have to get refund of 1660/-

(60 person and for 4 persons it will be 240/-
1900-240= 1660/-)

I have to get 1660/-,
But refund is initiated for rs1420/-

Refund the remaining amount.

Regards,
Jagadeesh
