Byju's — Cancellation of course and loan and refund initial payment

It was about 40 days since i'm requesting the byju's team for cancellation of my subscription/package. Call center people are arranging call in 72 hours. Bujus mentors are making a call and saying that they have forwarded my grievance to finance section. I have sent mails to resolve at the earliest through my email [protected]@gmail.com but they are delaying. This is happening since last on month but there is no progress. However, monthly installments of load is being recovered, though i have requested to stop recovery of installments.
