National Institute Of Open Schooling — Admission not done after full payment

Address:

National Institute of Open Schooling A-24/25, Institutional Area, Sector - 62, NOIDA Distt. Gautam Budh Nagar, Uttar Pradesh - 201 309

I had applied for senior secondary course in Stream 1 -Block 1 on 19/07/20. I have also paid the fee of Rs. 2050 on 19/07/20 and uploaded all required docs.
Three months have been past but my admission has not been done by NIOS. My dashboard is still showing "Document verification in progress"
On Sep 30th My dashboard notified to upload my docs again. After this I have uploaded the documents again but no further progress in admission procedure is seen.
I have not received any study material or enrollment number.
My ref no. is A[protected].

Regarding this I have sent emails to RD Bhopal also but no reply received.
Also the help line no. [protected] does not work.
Online help by chat is also fake. No reply is received.
I request for refund of my fee amount from NIOS.
