Honda Shine Bike — Poor service due to inefficient service persons

Address:

Thoothukudi, Tamil Nadu

I have a honda shine bike about 35000 kms ran, all my paid services in stipulated time promptly, recently more than three times serviced for one problem, ie blocking fuel or engine and suddenly block the speed at 50 km to 70 kms speed, lastly serviced on 11/07/2015, but no improvement, so again tried within 3 -4 days of service in the same dealer, till date no remedy, problem is present
