[Resolved]  Byju's — delayed delivery

I booked class 8th study material with samsung tab last month. They claimed that they take only 7 days for delivery but almost a month passed from the date of delivery then also i didn't got my order. Every time i call them they make different kind of excuses ans assure us with false hopes. I have also made the entire payment at the time of placing the order, now i have lost all the hopes and i feel duped by them.
