Byju's — Cancellation is not been done.

Address:

Bangalore

I had send email to byjus cancellation team to cancel subscription. Since there was no response from their side for cancellation, I have returned the course by my self to their office.
Still there is no response and im getting calls multiple times for paying the emi.
The parcel has reached their Office and I have the images of the receipt for the same.
Kindly do the needful and help me to Cancel the coures and refund as soon as possible.
