Livpure — Cancellation of subscription and refund

I received faulty LIvpure purifier which I requested to take back and issue full refund as per LIvpure 7 days refund policy but the LIvpure customer executive is deliberately causing the delay by stating that cancellation department will call, but they never did. I have been following them over call, email and their portal but all they give is verbal assurance. At this point I am sure the company is carefully planned racket to scam customers. They deliberately delay the service request so that either you give up and bear the financial loss or keep getting frustrated. I request you to take strict action against LIvpure.
