[Resolved]  Byju's — byju's sd card not working

I have paid the full amount to byjus, i had been told that i would be provided a new sd card but they are not sending the replacement. They are simply giving reasons saying my phone is not reachable, they are delivering today and all that, it has already be more than 20 days since they are not doing anything regarding this. I need some resolution on the same. I think they do not want to send so are giving reasons.
