Charging for maintenance of what?

Though our High Court has ordered not to charge any annual or re-admission fees in English medium schools, unfortunately, some of the reputed English medium schools are not following the instruction. Instead of using the words 'annual fees', they are using the word 'maintenance' to take the amount, and after receiving the amount, the schools are not issuing any receipt.
As a concerned parent, my question is, how can the so-called "maintenance" fees be BDT 30,000 to BDT 50,000? I hope the government will take necessary steps to exempt us from these unwanted and illegal charges.
