Indian Railway Catering & Tourism Corporation [IRCTC] — about tatkal ticket refund

I have booked a tatkal ticket and after successful payment status the message showed that ticket could not be booked & your amount will be refunded.
So i tried once again and same happened.
Again payment successfully done but ticket could not be booked and i received the message of refund.
And when chart of the train was prepared i received a message of confirmation of ticket booking.
But it was of no use to me then as i have already managed accordingly.
So i request the refund of both deductions immediately.
