Byju's — Neither taking any responsibility nor cancelling admission

I admitted my child in byju with lots of hope but all fake, there is no one to take responsibility of my child s education, about a one month before they message to provide next books but still nothing is happening, I requested them to cancel admition because child is not interested in their course, he is feeling burden with this, but they didn't. Later I got to realise that byju is a big team to cheat parents it's a fraud co. . it's fake and should be banned.
