Byju's — Byjus is not giving refund or cancellation

Address:

Bangalore

I have purchased byjus ias tab on sep 5 he told that i can return till 1 oct but i contacted him on 26 sep and he told that it cant be returned and he just blocked my number and then i contacted the returns and cancellations team and they r saying that byjus return policy is only 15 days and now it cannot be returned and then i started to call them daily mentioning everything what mentor has done to me
So after that cancellation
Department has not called me
They are not responding
They have cheated me
I want the refund of rs 65000
