[Resolved]  Byju's — incorrect syllabus

I want byju's to take the tab back and the material too. I paid for maharashtra board, instead of that they have sent cbse board. The materials are of no use anymore to me and my son. I have also called the customer care and the guy who came for the demo class, but no help yet. Lets just be very clear and take your tab back, and give me my money back since you guys are not interested in replacing it with the right product.
