Dear Venu,
first of all you need to take ITR acknowledgement of Return filed from your Accountant. After that you will find that your return is filed manually or through e-Filing, if it is filed manually than write an application to "commissioner of income tax " of your juricidiction stating all the matter and request him to issue your refund and enclosed copy of acknowledgement there with.
If you are staying in a big city like Jaipur then there is "ASK" centre (Ayakar Sampakk kendra). it is a centralised office of all juricidiction, fom there you can esaily get all required information.
Or if it is filled online than call to the toll free no. of CPC Banglore,
The helpline numbers for CPC are: Toll free – 1800-425-2229, and Phone Number – 080-22546500
