TVS Motor Company — tvs jupiter - bought on nov 5th

Before the day of diwali november 5th i bought tvs jupiter from arasu tvs porur. They promised me to give free helmet rs.1000 wave off from total amount as diwali offer, but both has not yet addressed and its been 1 month now. Im riding without helmet, arasu tvs is sole responsible if i met with accident.
Also when i asked for breakup of my total amount, they are give silly reasons as head office is not picking up the call, staff is on leave,... When i called their tvs finance they said the processing fee is rs.675 but the staff and manager of arasu tvs said its 2800, i have both the call recording, going to suite a complaint in court. Cheaters, fraud.. I give personal review of not to buy vehicle with this arasu tvs fraud dealer
