Indian Railway Catering & Tourism Corporation [IRCTC] — less amount refunded in auto cancel wl e-tickets

Reference to irctc complaint ids : 8439546 and 172739

I booked two tickets last days (17-mar-2018) having pnr number [protected] and [protected].
The charges for these tickets were 190/- per ticket. And those were in waiting list status.
As we know, if these ticket were not confirmed by indian railways after charting, the e-ticket having wl status is considered as invalid tickets and these are auto-canceled
By railways. Also i received a mail "the refund amount of rs. 130 per ticket will be refunded back to your respective account shortly".

Why the railways has deducted 60/- per ticket as these tickets were booked online and auto canceled by railways only?
Is it fair to charge on wl e-tickets if railways itself cancels the ticket. What is our fault?
In first line i have mentioned irctc complaint ids. As they are not providing any proper reason for this and not replying to this concern.

Request you to please look into the issue.
