St. Francis English Medium High School is cheated by the school management

Respected Sir/Ma’am,
I am the parent of a student who is studding in class 12 of St Francis English Medium High School, Machilipatnam Andhra Pradesh. Sir brings to your notice that the students of ISC are cheated by the school management. The reason why I am sending you the letter is to explain how the students were cheated by the school management.
Two years ago the school got the ISC permission, that time the management had promised the students and the parents that they will provide better education with qualified Teachers. But the management failed to do so, because the management changed the faculty for Ten times in those two years. This happened only because of wrong management skills and bad attitude of the management. As I heard the management was not paying the salary to the teachers what they were promised. Due to this the students suffered and still suffering. The correspondent is the main reason for all of this.
As far as I know most of the teachers who are teaching for all the subjects are not qualified to teach for class XI and XII. I was planning to file a case against the institution but before that I would like to bring this to your notice.
Names of the Teachers who are teaching for their subjects and their Qualification:
English: 1. Lissy Mathew
2. Pavani ( BSc, BEd )
3. Ramani ( MA Eng )
Telugu : Janaki
Mathematics: Naga Raju
Physics: Ambedkar ( B Tech )
Chemistry: 1. Praveena ( PhD )
2. Murali
Biology: Radhika (MSc Chemistry ) (Not Qualified to Teach Biology)
Therefore I would kindly request you to take immediate action against this school and save student’s life and I also request you to have a sudden inspection on the school.

Thanking you,

Your sincerely.
