National Institute Of Open Schooling — application status is "document verification in progress from 1.5 months"

We submitted the application, almost 1.5 months before, so far no confirmation, still the application status is document verification in progress. The toll free :[protected] is very bad, no one pickup most of the times, even if they pickup, the voice is not clear, they always say 1 week to 10 days will take. I spoke to them couple of times, gave the same answer. Really very disappointing. If our education system/nios itself is not sincere, then how students will follow the sincerity.
