2. In India defamation is actionable both under civil and criminal law. Under civil law you can file a suit for damages to seek damages on account of loss of reputation and also seek permanent injunction to restrain the company from further defaming you, whereas under criminal law you can launch the criminal prosecution of the company by filing a complaint case under Section 500 IPC.

3. The basic ingredient of defamation is that it has to be published. So you have to either examine as a witness or produce documentary evidence to prove that publication has taken place.
