[Resolved]  Byju's — tab not working

Tablet is not working properly, videos are getting interrupted in between. Called 2-3 times at customer support, they said you will get a call back from tech team within 24 hours. But i haven't...

From last 24 hrs i am struggling with this tablet. I have wasted a lot of time on this, moreover its weekend (The only time when you get extra hours to read). How will compensate for this?
