[Resolved]  Honda Unicorn — EXCESS AMOUNT. CHARGED THAN THE LISTED PRICE

On 8th March, 2010, I purchased Honda Unicorn from Aradhana (dealer of Honda two wheelers) at Howrah for Rs.66626/-. On further enquiry, it was found that they charged a few thousand in excess. Then I submitted a complaint with Honda at their personal website. They contacted a few days later and informed me that my problem would be solved soon. At the end of March, I got a call from Aradhana and they told me to give them a satisfactory note and informed me that the extrac price they charged was for the brokerage they had to pay to Motor Vehicles dept. for getting the Registration no.
So, again submitted a complaint to Honda but din't got any positive reply.
How can I get my money back ?
