Thank goodness you have finally taken my last advice.
You tried everything that was possible in your capacity and this is the LAST thing that you can do.
We all know that NDVO does not entertain any meeting with them. But there is atleast one case wherein the applicants had gone to NDVO (at Shantipath) in the morning ( I will confirm the exact timing for you). They had tickets booked and they had been waiting for PP for more than 3 months. They were asked the details of their case and they got their PP with stamped visa after 3 hrs.
Please also contact Anil.....I will let him too.
Please take all the docs pertaining to your case including your last GCMS notes and the recent one too (if u get it before the PPs arrive).
Hope this works out for you.
