Byjus — Cancellation of my Byjus product

I have placed an order with byjus and cancelled it later after a couple of days because my child moved to a different city with a different coaching institute and hence cannot study from Byjus
And I wanted to return the Byjus product because my child wasn't available later.
On thousands of calls and mails to the cancellation team of BYJUS they haven't yet cancelled my product and it's been 2 months now since I am trying to cancel.
If nothing further happens in a week I will file a police complaint against the same.
