TVS Motor Company — not getting original rc

I have purchased a tvs classic one month ago. I am not getting my rc. Registration authority has forwarded a speed post tracking no. But when u track speech post tracking no. It shows no confirmation available. It has been communicated to tvs showroom. They told we cant do anything. Providing rc to the customer is the duty of showroom, but they're not taking it seriously. The same thing is happening with many customers. Being a steemed organisation, it is ur duty to rectify customer problem and make good liaison with registration auhority. They also do not have suggestion/ complaint book to logue and resolve the issue.
