Byju's — False promise of mentor support

I have bought the Byjus tab learning for my child with a assurance from Byjus that the ywill appoint mentor and the mentor will keep in touch with my child .
But after the cancellation period is over they stopped the mentor service and hardly council with the student.

I also complained about their poor service on their portal but of no use.
They assured me for the progress of my child .

byjus cheating people by making false promises and then not responding to their calls.

MY COMPLAINT IS REGARDING THE FALSE PROMISE MADE BY THIS COMPANY.
