Byjus — Regarding cancellation of my subscription

Website:

Byjus.com

So I’ve been trying to contact the cancellation of the byjus team for like One and half months, there is no proper response, I’ve deposited 5000 in advance, and have an emi for 80000, the team isn’t responding properly, customer care is wantedly ignoring my calls by saying you will get a call back in 15 mins, whole day and their time ends . I’ve evidence that I’ve cancelled within 15 days of the given time . I don’t know why byjus reps are so greedy and cheap. I don’t want to pay a single penny and I want my money in return . What even ? No proper response and such disrespect too, I would like to sue this company
