Indian Railway Catering & Tourism Corporation [IRCTC] — Full Refund not given Even if Train is Cancelled

My ticket fare which they charged was Rs 731 including service charges. And one day before Journey Date, I received a message from them that Train is Cancelled. Now according to their rules mentioned on IRCTC website for Refund if Train is Cancelled, it is clearly written that full amount will be refunded. But what I got was just Rs 685. They deducted the service charges and didn't refunded that. Now my question is, even if I haven't used their services, then what gives them right not to refund service charges?
They should refund entire amount as this is clearly seen cheating passengers.
They just fetched Rs 45-50 from every customer who booked train tickets from IRCTC portal without even giving any services to them. This makes a huge profit that too without doing anything.
They are just cheating passengers and keeping money with them without any purpose.
This issue should be sorted out.
