National Institute Of Open Schooling — I'm complaining about their admission process

Honestly i thought this institute is a good option to continue my studies but I'm disappointed. I've applied for the secondary course on 02/03/2022 and it's been almost two months and yet my admission isn't completed. it always shows document verification in progress i mean when in the world they process the admission even i paid full fees i haven't got study materials and the worst part their helpline numbers they never pick calls nor they reply your emails it's not an institute for students it's a website for scamming poor students. I mean how should a student know what documents needed what to do or what to not . They just takes money and after that they don't care about you or your studies at all and the worst part of this there's not a proper channel to communicate with them and if you didn't submitted your documents of failed to submit your admission will be cancelled and they won't refund you a penny. It's just a clear way of making money by playing with students futures.
