SBI — transaction money

Address:

Rupnagar, Punjab, 140001

I booked an online railway ticket through irctc website, paid through SBI netbanking.
money got debited Rs.1630.but error came I cant able to book the ticket, RAC6 was ticket status.
Then I tried with Debit card the same thing happened, so stopped booking.
A day later I booked my ticket in the meantime ticket status raised to RAC 46.
I need to register this complaint against SBI?want to know were mistake happened? If not their mistake I will proceed filling against IRCTC.or my mobile network operator
