Honda 2 Wheelers India — Manufacturing defect

Address:

Bangalore, Karnataka, 560056

I purchased a honda dio vehicle on[protected] from m/s turbo honda, nelamangala, karnataka.
From the day-1, i was facing the problem.
I had visited to m/s prime honda, nagarbhavi, bangalore
They said "it is new bike, need some time, drive it till first service then we will rectify it".
After that i serviced my bike after 30 days at m/s prime honda, nagarbhavi, bangalore, but they have not rectified the problem as promised by them.
After my repeated visits to them they saying it will cost 4500rs.
Due to wrong handling of the vehicle at the time of delivery this problem is occurred.
For the mistakes done by the dealers, why should i pay the penalty?
