Byjus — No refund after cancellation

Website: Byjus

I have been dropping mails to get my refund from byjus. The counsellor that made me enroll into a course stopped taking my calls or responding over texts right after i made my payment
It was a course that i never wanted to enroll in the first place.
I paid a hefty amount and i have been calling them and everytime they tell me that they will look into it and arrange some phone call but i still haven’t received any money back
My exam preparation is on hold because they aren’t sending me my money back
This is highly mentally taxing and inconvenient
