Byju's — Lack of service

I had enrolled for BYJU’S IAS coaching which is valid till 2026. The course includes live online classes which is valid till the year 2024. However, I have not been given any links of the classes and the application also does not display the time table and live classes links. I have tried to reach out to the customer care but in vain. I have not received a single call back till date even after me contacting them for multiple times. I’ve been paying the EMI for the course but there has been lack of service on their part. Hence I would like to complain about the same and would want them to pay for the damages after resolving the issue.
