Nsdl E-Governance Infrastructure — pan rejected for no reason

Pan application - ack. No. N-[protected]

This is the 3rd time i am sending my documents to these guys. They send me an email stating the following as the reason

"copy of office identity card of mp/mla/muncipal councillor/gazetted officer is not attached alongwith the certificate provided as residential address"

I know a copy of office identity card is to be attached. I had attached both the driving license copy and pan card copy of the gazetted officer. I had stapled it with the address proof. I am fully sure about this since i checked everything multiple times because these people have given such reasons twice before.

Now 3 times i have wasted my time and money for application and postage. And this time all because nsdl official couldn't find the document stapled with the original.

I even sent them an email. They did not reply.
