Byju's — Regarding Cancellation of Admission

For the past 1.5 months, we are trying to cancel the admission of my daughter, but they are doing nothing. We have sent too many emails to them but they are not doing something.
Here are a few details:
Order ID: Not Received
Student Name: Lavanya Sharma
Registered Mobile Number: [protected]
Registered Email ID: jitendra.[protected]@gmail.com
Not even the refund has been done yet and they are calling and harassing my wife on phone.
