against father and its staff

Location/place: damoh

Name of company/service: st norbert school

Respected sir,
As you know your school is also finded in Madhya pradesh state – damoh district whose father is father bilfrade my name is sandeep vishwakarma and my problem is that marksheet total was added incorrectly by mostly class teacher. This matter when I open in front of father they does not took action against teacher. Same done to my cousin son harsh vishwakarma her marksheet total was also wrong and my son who was in nursery his marksheet total was also wrong. It means the teacher which was adopted by father if they did mistake he did not take any action. Student and parents are complaining teacher staff but father only says us that “I will see them”.
I only request you to plz send any strict father or staff that can look over the activities of teachers and listen to student parents because the teacher mostly from hindi medium and they did not know how to talk in English. The grammer does not taught in this school any student don’t know tense then how they can speak or correct grammatical mistake of English.
Second thing is, in damoh there are two store were books of st Norbert school syllabus can be find on Ganes store keeper does not have books and second sadhna store keeper has books but he is selling it on his price more than the price available on books. It means father is getting more attention on commission.
