Byju's — Byjus products

Address: India

Hello,
We have subscribed BYJU's for my daughter (Aarohi Abhijit Chavan) from grade 3 to 6 in Jan 22.
After try of several days, it seems that it is not effective learning as well as we feel that it is not useful subscription.
We would like to cancel the subscription. Till date we have paid lot of our hard earned money. But now we want to stop it.
Please cancel the subscription as well as stop the EMI/monthly deduction.
We tried to call and send many emails at "[protected]@byjus.com" but nothing happened since last 2 and half months. Please stop the EMI getting deducted from my account. And check if the amount paid can be refunded or not.
