Panind — I need refund

Address:

Chennai, Tamil Nadu

I have applied for new pan card application through online and i was charged amount of rs. 499 and it is very high.
I have sent all the required documents correctly through speed post (Which costed around rs.100). Now i've got a mail that my application is on hold and there are additional documents required and i have to send all the documents again. This will again cost me around rs.100.
So i requested for cancellation and refund through mail. But i'm getting only automated responses. I need the full amount (Rs.499) to be refunded as soon as possible.
