Central Board Of Secondary Education [CBSE] — Complaint related to mark sheet

Address:

Kanpur, Uttar Pradesh

Sir,
I had passed my intermediate from durga prasad vidyaniketan,, kanpur..in the year 2014. But when i received my intermediate level mark sheet from school.. I found a difference in candidates name while comparing my 10 class and 12 class mark sheet. The candidates name in 10 class mark sheet is abhishek kumar yadav. But in 12 class mark sheet the candidates name is abhishek yadav. So, there's an absence of kumar in intermediate mark sheet... I had given application to the school authority for the correction of name. But no action has been taken yet. And the principal of school ms jasbir bakshi always misbehaves with me and my parents. So, kindly bring out a solution to pacify my problem.
