Byjus - Course cancelled within a day and still no refund

Byju representative Mr Jagadeeshwaran contacted me on **nd April **** for JEE course for my kid who is studying **th, (even though my kid was not interested). I called him home. As per him if we don't like the course we can cancel at any time. But later I found in their terms and conditions it is given as ** days.
I believed him and ordered for the course on **rd April ****. He took my Adhar card, pan card details and also a signature for loan application. He told the course fees is ***** rupees and I paid net banking transfer for **** rupees.
After registering the course I discussed with my colleagues and teachers and also surfing online I came to know that the course is not suitable for JEE, so mailed Byjus on **th morning for cancellation of the course, I received mail from the support team and ticket number for my mail is *******.
From Byjus, Mr Jagan and Mr Mukilan contacted me and I clearly told them that I am cancelling the course and no need to send me the Lenovo tablet and to refund the advance amount of **** rupees. But they are insisting me to take the Lenovo tablet and not interested in cancelling the course. As per the terms and conditions within ** days I can cancel the course. Today it is only **th April **** (* days gone) still, they are not accepting my cancellation. Byju's are not respecting their own terms and conditions. Their only aim is to cheat the customers. Byju is a fake and fraud company looting and cheating people in the name of education.
Today I received mail from my bank for Mandate registration and payment for remaining ***** rupees from Paysense (finance company partner with Byju for providing loan). I also mailed to Paysense stating that I have cancelled the course and don't want to proceed with the loan. But still, Paysense proceeds with the loan.
I have all evidence (both audio and mail evidence for my cancellation).
Request to all parents who read this please don't allow any Byjus representative to your house. By sweet talk, they will convince you and cheat you.
Request Byju team to stop such cheap tactics to earn money and to respect their own terms and conditions and pay back my money.
