Yet not received the 5% cashback, sir i had taken a package of study material from byju's representative mr aryan, he told me to pay all amount in one go and then you will get a 5% refund amount of the total amount. I had told the representative several time but could not get the money, even though i gave him the bank statement, still i wont get the refunded amount.
