Ebiz.com — Fraudulent transaction

I have been sold a course by ebiz.com on the pretext of it being a life changing set of professional courses and has ISO certification with no active cases on their company but after purchasing I have been constantly contacted by their representatives to add more people to this so that they can earn a referral bonus as well I can get a cut but eventually the company is a fraud and defrauded me for ₹16815 and now all I want is justice and refund for the same.
