Byju's — No proper response from BYJUs

We have following concerns against BYJU and need a quick refund for the entire program what we have purchased:
- The answers given by the experts in BYJUs are 70% times wrong. They will not be able to reason out the answers properly and explain it to the child.
- When placed a request for call back to solve a query of the child regarding subject, there is no call back done from BYJUs.
- Out of 1 year, we have placed multiple requests (more than 20) for doubt clarification but have received call back only twice.
- Even those 2 times the expert calls, he has time limit of 5 mins to speak to child which is a limitation to explain the doubt to the child.
