Panind — refund my 499 due to no correction my pan card

Sir,
I applied for my father's name correction in my pan card one and half month before, but it is not corrected. I mail the photo of the uncorrected pan card to the respected mail id.
I kindly request you to refund the correction charges of pan card ₹499, which i paid, but the correction was not done in my pan card.
Today i received my pan without any correction after one and half months.
Please refund my amount of ₹499 as soon as possible.
