National Institute Of Open Schooling — Not being provided with enrollment number

Sir i'm a student of class 12 from nios i took admission last year 2020 and my exams were suppose to be held this year but got cancelled due to covid and our results were based on tutor marked assignments. All my fees were cleared and all my documents were given to the study center before time. But i didnt get my enrollment number that was suppose to be provided to me by the boards later when i contacted the boards they told me that my documents were missing and as a result my admissons were pending and i need to reapply next year with a payment of rupees 750. Sir its npt about the money that they afre asking its about my loss of 1 year when there was no fault of mine. If the boards knew that my documents were not submitted properly they should have contacted me and informed me. The fees of nios is 2450 but the study center took 15000 from us for admission and after paying also they didnt confirm my admission. Sir please lookinto the matter im a common student a loss of 1 year would be a great loss for me
