Panind — repeatedly asking for same documents to issue duplicate pan and delaying deliberately

The mail id. [protected]@panind.com on which i applied for pan card, i get request to submit scanned documents to process my pan card and seems to me a spam. The site have changed rs. 499 to issue a pan card but they keep on asking the same documents again and again this is delaying. My order no is order no. Ab - [protected]lo. It is now over a month... And i fear documents will be compromised.
