Hello, writing a review/complaint on consumer forum is totally different from filing a case in consumer court. One has to draft a complaint mentioning all the facts along with all the evidences and submit the same in the consumer court (as per jurisdiction). But I would suggest you to consult a good Lawyer and send a legal notice before going for any legal action against the company and thereby file a suit in appropriate consumer court. As far as possibility of winning of the case is concerned, nobody can gaurantee you of winning the case as it depends on the facts and circumstances of the case but you will surely win the case if you have reasonable evidence to prove your facts.
