Yamaha Motor India — Behavior of the staff and service

Address: 560102

I was publicly harassed by the staff and most important of all the manager of the Orion Motors (Agara Post) Yamaha service station. He publicly called me a Liar, defamed me in-front of other customers and service staff. He was not at all helpful and polite was super rude. I want to press charges and file a legal lawsuit against the manager and staff member Mr Hari as well as the service station. Please help me for further actions. Publicly shamming me as a customer was traumatizing.
