Byjus — Registration cancellation - no proper response

Requested for registration cancellation and not getting any proper response even after multiple mails and multiple calls to helpline. It's been 50 days now I have raised the complaint but no proper response from byjus and amount got debitted without any prior notification. The lady who did registration is not responding even when tried to call. I need an immediate response from byjus to confirm my registration cancellation.

Each time they will tell to wait for 24hrs and will get call back. But no response from them yet and it's really very annoying.
