Byju's — product expiry date

Address:

602, Gokul Niwas,, R P Nagar, Matunga Labour Camp, Matunga,, Mumbai City, Maharashtra, 400019

I had bought the tab of byjus for std 8 to 10 for 66000 rs. The sales man said the life of the product is till the life span of tab and any damage to tab will be fixed by byjus at minimal cost.

No after the purchase of the product i can find there is expiry date on each standard for 1y. That is after reaching 9 student cannot access content of 8.

This is really a big cheating by the company. Now when i call byjus i am not even entertained by them. No one is there to help with procedure to cancel the product or extend the life of product.
