Name misspelled on Visa Page

My father has collected my B1/B2 Visa yesterday (January 14, 2015) from Pune VFS office, we just noticed today that his name is misspelled on Visa Page, should be “RAMAKANT” but got it with an extra ‘A’ “RAMAKANAT”.

Could you please give me the procedure to correct the name in Visa?
