Central Board Of Secondary Education [CBSE] — correction of father's name in 10th board examination mark sheet.

Few days after we received the admission card for 10th cbse board exam, i realized that there is error in father's name.
I wrote mail to school to correct, for which i did not received any response.
After reminding them, they replied they have transferred my complain to concern section.
Then in june end i received call from school saying that there was mistake in passport and cbse takes names as per passport.
(Here i would like to bring notice that school made up fill all details in separate form student;s name, parent's name, etc., this was confirmed by class teacher with student for several times.in this we had given correct father's name detail)
Still i requested them to please help, for which they told me to submit corrected passport.
Which i did and submitted on 6th july 2017
Thereafter i did not get any reply from school in spite of my reminders.
Then the original mark sheet and relevant documents were given to us 26.09.2017
I wrote mail same day and called school next day.
I managed to talk with one concerned and he told school will respond/call me back.
Which they never did and i called this gentleman again.
For which he told me that they have forward to cbse and waiting for there reply. And he also told me that he discussed my case with head of section, and she was of the opinion that error in father's name will not affect.
On 10.10.2017 i went to meet hos (Bps doha).
She was of opinion that not possible to get father's name corrected on mark sheet now from cbse.

I am requesting cbse to please provide me with correct mark sheet and all other relevant documents with correct father's name.
Also when school took some written confirmation about parent's name and other's detail to submit to cbse, and to which we provided correct details why our correct details didn't appear on our relevant documents. And as of when we are approaching school they are saying it is almost next to impossible for getting such corrections done from cbse???
