Hero Motocorp — complaint about the service center

Address:

New Delhi, Delhi, 110049

Hey
This is regarding the service center name jk enterprises in amar colony, i took my scooty there for servicing around a week ago. Despite telling them about the problems that i am facing like suddenly shutting of engine, pickup issue and scooty's horn, they didn't repair it and charged me around 1300 rupees for nothing. I took my scooty the very next day for a check up with the same issue but they didn't did anything. The engine is over polluting and i faced mamy problems to obtain a puc.
The manager at the service station is not very supportive. So i am looking for the help from you so that i could take my scooty for long diatance ride.
Thankyou.
