School is not refunding annual and stationery fees after withdrawal

Hi Sir/Madam, We took admission of our kid for LKG in the month of January 2020(Pre-Covid situation). We have paid Rs.33500 for annual, resource fees(Books,Uniform,Stationery) and day care advance.We are withdrawing from the school as we want to continue with home schooling this year.We have attended 1 month(around 10hrs) online classes in the month of July, after that school has discontinued the classes as we have not paid Term fees. When we approached them for the refund of Annual fees and day care fees advance, they are denying stating that we have utilized the services for a month, We have not utilized any of the school premises/services for this academic year. And also we are informed that the school is refunding the Annual Fees and school uniform/stationery fees for some of the other parents.we have not availed any extra benefits from the school except for 10 days of free zoom online classes. Can we lodge a complaint in this regard on school for denying the refund in consumer forum, please advice us on how we can proceed with this.
