National Institute Of Open Schooling — duplicate passing certificate

Address:

110017

My name is tushar gurung. I have been trying to call your toll-free number for last 1 hour it's saying line is busy. How is that possible.? I wanted to apply for duplicate 10th passing certificate just wanted to know the format of affidavit and i have other questions to ask. Sometime it says line is conjested and wen i get to hear the ivr line just gets disconnected. How come toll-free numbers can be so busy. I also call other toll free numbers even if they are busy your call goes on hold. But in your case it's hard to reach you.
