Website: Byjus.com

I have purchased a course for my Sister, Kirti Himirika .
This is the reference ID Mail regarding my cancellation
*ref:_00D2w3yRgl._5009G3D3eM:ref *


which include class 8th, 9th and 10th. But the product and tablet device received is not as my expectation. And also I told them about my financial situation and want my sister to join in a boarding school near my locality but they crossed the line asking for proofs as “if it’s mentioned in their policy that when we need to cancel a product we need to provide proofs of reasons and our personal choices and information”.
They lied that if I don’t like it it will be a smooth cancel process. Everyday there is a stress and thought of will This cancelled or not, it’s draining my energy
And more of Byjus never reply me over mail.
I need this to be cancelled immediately.
