Irctc — ticket not booked however amount deducted

Website:

IRCTC online ticket reservation link

I was trying to book a Railway ticket on 5/19/18 using my CITI Bank debit card, but I was not successful 3 times, and all those 3 transactions were declined. However, The amount got deducted from the my CITI bank account. Received messages from the IRCTC that the amount would be refunded as the ticket was not booked.
After that I checked my account there was a reduction of RS. 10, 140.
I am trying to calling IRCTC helpline number but there is no response.
what should I do?
Please help me.
