Vespa — vespa 150 slx engine problem in 20k kms.

Address:

560100

I purchased vespa 150 2 and half year back and it had running off problem from the begning.
I was complaining from the 2nd service but it was never repaired to my satisfaction.
Sometimes, immediately after service I brought back the vehicle back to service center again.
Now, Dealer and RSM is telling that, engine is damaged. It was damaged from the begning but never taken care by service
Now, warranty is expired and now I am being asked to pay for repair.
RSM is not entertaining as warranty is expired and not admitting the fact that I was reporting the problem from the begning
On one hand you take warranty of 60K for engine, while mine is just 20K Kms.
I suffered with the vehicle for two and half year constantly, no body in my family use the vehicle as it stop on the road any time.
I have dragged it to service center many times by myself.
whom should I contact? Is there someonoe in Vespa who care about cutomer?
