I bought the product and after couple time usage. I found my kid is unable to use the app due his tight schedule it ws hardly 15 days. I tried to contact cusromer care and cancel they were of no use. Lady whi sold the product assured to fix but after a month of follow up she denied and now as per their policy after 15 days u have to use. No cancellation. I will sue and make sure Byju Ravindran changes the policy and cancel/refund asap.
