Byjus - Byjus deducting my emi even after cancellation of subscription

I was contacted by byjus councillor logesh n convinced me to take a trial of ** days of early learning program by byjus he said it’s totally free but asked to register my card if I want to continue the subscription if I cancel the trial the emi would not be deducted he said . During the trial period I cancelled the subscription initially they tried to convince me to continue subscription but I did not . So after that they are not even replying to my number n my emi is getting deducted from my account . I am totally helpless .
