Byju's — To cancel my subscription

Hi.
Name - Chaitrali Dangre.
Ph.No. - [protected]
I want to desperately cancel my subscription.
We took 8th, 9th and 10th grades live classes program with mentor. Last year (8th grade ) we attended live class but for this year (9th grade ) they are saying you r not having live classes program as well as for 10th grade also you are not eligible for live classes.
When we took this subscription we ask for live program for 8tt, 9th and 10th class. The sales person how sell this to us he cheated with us even he didn't send us invoice copy of payment. He added 7th grade live classes in that program too. Which we not attend.
From last 3 months I am in contact of your multiple mentor, representative, senior members etc but no one is having correct solution. I thought if you understand what happened exactly with us you will solve this problem. But no out put from last 3 months. Now I am fedup to talk every day same thing. So pls cancel my subscription and refund me my all money back. Because here we got cheated from byju's.
