In convenience on purchase of two wheeler

I had purchased a motorcycle from Viniline Engineering Pvt. Ltd. Baguiati, Kolkata-59, on 28/04/2017 paying full onroad amount with insurance. But the dealer is still unable to give my road tax papers and vehicle registration number. Insurance without number has been done. That means even after giving all the charges I am unable to use the vehicle since one and half month. I have approach the dealer several time. Still they are working on this. I spending lot of money for my daily convence. I want a quick action against the dealer for my harrassment and compensation for expenditure
