Byju's — cancellation of product

Address:

Bangalore, Karnataka, 440013

I had been following since long but not getting response from byjus, twice
They commited regarding cancellation but again refused to do so, they are asking for proofs which i dont have as i was not aware of these kind of fradulent activities of byjus, the sales team make false commitment that you can return it but dont pick the phone they delibrately do this to fool people.
