Central Board Of Secondary Education [CBSE] — Fees structure

So far to my knowledge education is not a business in constitution of India.As a parent I have responsibility to give better education to my children for their future. so I have joined them in one of the cbse school in Tiruppur district Tamilnadu.My complaint is about no proper fees structure before and even after covid.Not only one school damn sure all schools in tamilnadu like this.Only online classes going in this covid situation but they are asking Rs.75000/ Year for 8th grade.before it was Rs.100000/year.
If we failing to pay, school disconnect online class and telling won't allow to write final exam.In this stage as a parent we are facing so many problems like unemployment and salary reduction etc...I want cbse board should freeze term fees for this covid period and even after for regular schooling.
