Byju's — Partially amount refund

Address: Bhubaneshwar

I have subscribed byjus premium course for my Daughter Miss Anshika Lodhi for 2 year (std.4 & 5) . Then I have cancelled the subscription as per Byjus terms and conditions which is told by their counselor or mentioned in website byjus. I.e. if cancelled within 15 days from orientation byjus refund 100% amount. But they return to me partial amount.
Retain my 10000/- for product of byjus learning station and they can not take back product alongside my amount not return.
