Consumer Redressal

Hello Sir/Madam I am a student of National Institute of Open Schooling (NIOS) and i had given exam in feb 2020 but in my online result one  TOC (Transfer Of Credit) subject was not added i.e Environmental Science, for which i called them and emailed them continuously day and night for about 10-15 days as soon as the results was declared, but i did not get a proper response from them. And finally i received a mail after 15 days saying that the TOC subject i.e Environmental Science, which i had applied for, is rejected. How can they reject a subject, when they had already confirmed my admission along with the TOC subject. My admission was confirmed on 24/1/2020 and they reject a subject on 14/8/2020, how can they reject after confirmation of admission and after the result? I request you to help me with this issue as I will lose my admissions for this year  as i have already applied thinking that they will update my result. I want to file a case against NIOS because this is not acceptable that they confirm my application with TOC subjects and then reject my TOC subject. I am attaching my confirmed admission form wherein you'll find the TOC subjects accepted by them. I am hoping to get justice on my case. Do contact me for further proceedings. Thanking You Shareen Patni
