Indian Railway Catering & Tourism Corporation [IRCTC] — Booked a train ticket in Jan Shathapdhi train but seat not confirmed

I booked a train ticket on 02/11/2016 in irctc for travelling from davangere to bangalore (sbc) on 06/11/2016 for myself and my daughter, who is five years old. i booked full two tickets for both o[censored]s and paid rs. 343/- through net banking. but it shows ticket are not confirmed but in waitinglist 31 & 32. till on 06/11/2016, i won't get any confirmation or message from irctc for my journey. i travelled that day through some other train with risk. on 07/11/2016, i got a message from irctc saying my train ticket is cancelled and an amount of rs. 200/- will be refunded soon. on 08/11/2016, i got a refund of rs.200/- only. why irctc taking full money while booking the ticket without confirming the seat and refunding only less amount, without giving any reason. i want my full amount to be reimbursed within one week, otherwise i while take further steps against irctc.
