Central Board Of Secondary Education [CBSE] — complaint against high registration fees demand

Respected sir /madam,
I would like to inform you that oriental public school with affiliation no. 2430139 has revised the application and registration fees as per their own profit! The following are the details:
For class 9 - rs600 per student
For class 10- rs2500 per student
For class 11-rs 700 per student
For class 12- rs 3500 per student

The school has rigorously increased the fees and denied the instructions given by cbse! The school is not allowing to show any receipt as a proof of the payment! I know they are looting us and playing with our future! This is becoming too much as people under bpl category are unable to pay the registration fees now! The higher authority is now threatening the students that if they complain or refuse to pay it, they will surely give them less internal marks! We are hopeless now, it's a harassment for us!

I would highly request you keep my identity secret otherwise the school will snatch internal marks and keep threatening me! Pls look into this matter seriously and as soon as possible! An early response is highly appreciated!
