Pan Card — Pan Card not recieved for the last 2.5 yrs

To the authorities concerned:-

I had applied for the Pan Card 2.5 yrs back. I got the Pan Card Number in time, but have not got Pan Card till date. When I tried to reach out to the customer care help line at [protected]. They don't take the calls. by chance, one day, some one ansewred my phone, then he replied that my documents are not matching . Then, as per his suggestions, I faxed the documents to NDSL, but did not get any response. I again touch based with customer care. they said: they have not recieved any fax.
on their suggestions, I sent the documents again through courier. Since then, I am waiting for their reply. I have tried a million times to call them up, but no replies.

Here are the details:-
My Pan Card Acknowledgement #: [protected]
My contact #: [protected].
Please respond to my complaint, as I need the Pan Card urgently.

Thanks,
Vikram
