Byju's — Unnecessary calls

I downloaded the app to register for KBC. we got option to register only for one day on 10th Sept and that day we gave quiz twice after that on 11th Sept we didn't get the quiz option active. After that i started getting calls that i have downloaded the app and saw few videos so if i want to buy course for my child. i told them i am not interested in buying any course, videos are nice but don't want any tuition right now. after that twice in a day or minimum once in a day i am getting calls, the moment we watch any video on app next day we get call. You kept videos open for all, if you want people to buy then don't keep the app free we will not download. But Byju's can't force people to buy their tuitions by calling just because we watched their free videos. Byju's told me that they have campaign going on so if you watch video you will get a call. this is wrong, you can't force someone to buy their courses, then don't keep your app free we will not download in the first instance. Providing mobile numbers i got call from BYJU's ([protected], [protected]
