Reference no is a[protected]. As per nios norms, i've sent all the relevant documents to nios kokata regional office too. I haven't received any study materials so far. Repeated mails to the regional office kolkata go unanswered. I have even tried communicating to the chairman's office but still no go. There's also a vigilance email which i tried communicating with but yet no replies. They dont reply to emails, they don't pick up calls.
