Sir a full WL e-tkt after chart preparation is auto cancelled by IRCTC and the refund is sent back to the account that was used for the booking. ideally the reservation charges is what should be deducted.However in your PNR it is not going to be autocancelled as one of the passenger is moved to RAC. if tkt is taken from counter then you can go to the nearest PRS counter with 24 hours ( not sure though) of the trains departure and cancel the tkt. If you delay then u might have to file a TDR.
