Indian Railways — amount not refunded for cancelled ticket

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201310

I cancelled ticket when it is not confirmed in the train and at that time it was shown that INR 1135/- will be refunded and I can see on irctc website that it is showing that amount is already refunded although it is not refunded yet. I can't see the amount in my bank statement. Kindly let me know why it is not refunded yet moreover also let me know to whom I should contact for getting the amount back as soon as possible.
