Pan card
Not received

I am a senior citizen and have applied for a PAN card on 6-10 on- lineand sent the required paper on 8-10 by post. But on checking my application status on internet it always says that the papers are still awaited. I dont understand it is 15 days but the depptt still have not receivded the papers. Please let me know for howmany days more i have to wait or if necessary should I send another set of paper per speed post.

I hope to receive an early reply.

Thanks.
