Byjus — sd card not approved for class, 11 & 12 full payment done

We had got byjus for classes 8-12.
Now that my kid had finished std 10 i realised that another sd card is needed for class 11 &12.
When i contacted the customer care they said it was delivered along with the tab.
I don't that the sd card.
Sharing delivery of the tab no specifications regarding the items in the box is told.
How do we know what is inside before open it.
#byjus should have given a check list for the products it sends
# why should the syllabus be given one year ahead when there are so many changes in ncrt ever time
# we realised that the kids dont have much time to do both school work and byjus.
# byjus does have a very good marketing team that knows the pluse of the parents well
