Byjus — I want to cancel my IAS subscription programme

I joined the BYJUS IAS coaching programme in the month of November 2021. A counsellor from BYJUS named Rishabh Kumar came to my house and informed me that I could cancel the programme at any point of time if the services were not satisfactory. After 10 months of continuing the subscription I realised that I do not want to continue and have even gotten a job. Now they’re telling me that I cannot cancel. I have even received messages stating that if I do not continue paying the EMI my CIBIL score would be affected. How can I make them cancel my subscription? Please help
