Byju's — Help me to cancel my Subscription

Hello my name is Nilesh Bhaisare and i have purchase 2 teacher course for 9th class and 10th class with total of 43000 for my brother and i he had done classes for 2 months but later he is not comfortable with it, so we decide to cancel it and then i had send an email to byjus that we want to cancel the course but the costumer care said that it is not possible to cancel the subscription they are saying that you should have read the contract. so i stop the payment for this month because byjus didnt cancel my subscription and had actually taken the screenshot of the policy and i didnt find the cancelation word. i also seen the cancellation policy which is on the official website of byjus that it exists.
I dont want to make any issues with Byjus and myself i Just have to cancel my subscription not because byjus is not good but because of the child interest in it. i dont want any refund the only thing i want is to cancel the subscription and if there is any charges then i will also take notice of that
I hope Byjus will do this and i will co operate
