Byju's — issue in cancellation

Address:

BYJU'S, 110077

I rajiv sharma father of diya sharma who registered for the byju's product and received the package on 27th feb'20. Unfortunately the content i couldn't find fruitful, and hence would like to get the product returned, and this i have planned after rigorous attempt to view all the listing and documents available on the app. I have been informed that in case i am not satisfied with the product, there will a no question ask policy and this would be taken back. Now from sunday since i registered my interest in cancellation i have been continuously being harassed. I have got calls, they hung up call on me without giving me any update on cancellation. It is my hard earned money and the commitment on return policy is not being adhered. Please suggest. My receipt number of purchase is tnl[protected]. The person who closed the deal was aashish verma[protected]
Thanks in advance
