Byju's — order cancellation and rude behavior and refund declined

After multiple forced sales, i brought the subscription for my son for class 4 to 8, after few days i found product not making sense and it no way meeting the requirements. I called on 15th day and sent a mail on 17 the day, but refund is denied
Even our hr head feel cheated by then false commitment by byju personal.
