[Resolved]  Byju's — hardware/software issue

I bought the product recently and i cannot connect the tab to wi-fi. I have tried reaching their sales person and it says number not reachable. Seems like there is some issue with the tab. I was told that if we connect once to the internet, her mentor will be able to track my child’s progress and will be able to help him better. He has started using the app but not able to connect it to the internet. I want this issue solved as soon as possible. I have waited for a response for quite some time now. No one called me and i gave them a call two days back and asked for replacement. She said concerned person will call me back within 48 hours and help me with this but still no word from them.
