Byju's — Byjus poor customer service.

I started byjus for my daughter. The initial part their approach is good, after 15 days they started showing their poor mentor support, so far it's been many mentors calling at the time of 7 or 8 pm when my daughter is not available. It's been 40 days as of now, we are not interested in continuing as my daughter is not showing any interest on the product as she was only at age of 9, I don't want to make more burden on her apart from regular school syllabus.
I am calling them for cancel the subscription and I am ready to return the kit.
