Byju's — cancellation of byjus product

My byjus subscription has been enrolled in the name of aryan goyal
My registered phone no is [protected] and [protected]. With due respect i would like you to pls cancel my registration and refund my money. I spoken to my mentor regarding this but they say it’s been more than 15 days so they can’t cancel it. But i was regularly informing regarding my issues with the concerned person whose no is [protected]
Every time he use to convince that to try for some more time. But we are not comfortable with the online class and as know he is not responding so i request you to pls cancel it and make my refund asap
Thanks
