             " In company there were no large TDS as per 26AS and refund is there due to advance tax and large amount of depericiation."
The case is for company's refund with its 26AS data, and selected as per some abnormality in line with similar other industrial data stored in departmental database.
In your case it  may be genuine, but I don't see any other reason.
