Byju's — non response from byju's on the request of cancellation

Address:

BC Knowledge Park, Tower D, 4/1, Bannerghatta Main Rd, Bhavani Nagar, S.G. Palya, Bengaluru, Karnataka 560029, Bangalore, Karnataka

I have purchased the byju's classes from 9th to 12th. I received the byju's kit on 10th july 2019. After going to the content in the tablet my child said that i am unable to understand the content. Then on 23rd of july 2019 i made a request for the cancellation of my subscription and requested the byju's for the procedure of returning the kit. But byju's didn't responded.
Please cancell the product and refund the amount.
