Central Board Of Secondary Education [CBSE] — School not providing TC/ School leaving certificate

Dear Sir/ Madam, My son was reading from class 5th on wards. Now he appeared in class 10th CBSE exam and due COVID-19 govt had changed the mode of exam. I have paid all fees amount for class 10th while situation was critical due COVID-19. Now, without informing and consent of parents school has increased fees and charging Rs-25000.00 for new session. We are not agree and unable to pay such fee hike. Now we are requesting, to providing TC/ School leaving certificate, but school is demanding for 3 months fees for new session i.e from Apr-21 to June-21. CBSE has declared result in Aug-21. I request u to please, help me. I am a poor person and running a family of 07 members fro hand to mouth.
