Central Board Of Secondary Education [CBSE] — Additional Subject Change In Class 12th

Respected Sir/Madam,
I'm a student of class 12th of Sacred Heart Co-ed School, Indore. I'm willing to change my additional subject and I have provided my subject change application to my school in the month of May 2021. I had some words with the CBSE Board Bhopal and they assured me that my subject can be changed but for that purpose I have to inform my school. I informed my school but my school denied that my subject can not be changed. After a lot of efforts they accepted my subject change application but they didn't pass it to CBSE Board. And now I'm in confusion about my subjects that whether it's going to get changed or not. My school is neither cooperating with me nor they are providing me any assurance.
