[Resolved]  Yamaha — Invoice not received

Address:

Mumbai Suburban, Maharashtra

I am Anshul Bhatia. I had bought a Yamaha FZ-16 on 17/10/2010 from THOMSUN AUTOMOTIVE (Sub-Dealer for Yamaha Motors India Pvt. Ltd.), Andheri-West, Mumbai.
He has given me all other documents like Insurance, Bike registration tax receipt, Bike manual and warranty book etc. But, he has not given me the YAMAHA INVOICE for the bike.
So, i am not sure whether the bike given to me is a new or an old bike.
I think, INVOICE is my basic right and i should be given an invoice for Rs. 75,500.
I had asked him for an invoice again and again, but he said he has not received the invoice from the main dealer. I dont know, how can it take so long?
Please help me.
What can i do about it?
