Central Board Of Secondary Education [CBSE] — Maintenance charge is being taken even after not attending school in pandemic

Our school, "G.D.Mother International school, Gola road, Ram Bhajan Market, Muzaffarpur, Bihar" is charging us maintenance charge. We complained about it to the management but no one responded. We are not attending schools due to pandemic, but still we are forced to pay the maintenance fees and on top of that they are increasing fees every session. Our parents are not economically stable to pay 2000 rs for a child studying in class 4. I humbly request you to look at this matter. Please look at the matter and please help us and i request you to not reveal the email id or name to school faculty
