Tvs Motor Company — mileage problem in jupiter

Address:

Uttam Nagar, New Delhi, Delhi, 110059

I bought jupiter last year from s. K. Traders. Around after one year i checked that there is milage problem in my jupiter. It givers 20 km./ltr. I visited tvs service centre dynamic motors, navada regarding this milage issue 10-11 times. Every time they serviced my jupiter and said that now it gives 40km/ltr but everytime when i checked it gives 20-23 km/ltr.

10-11 times for same problem. It's really surprising that the problem is not solved after so many complaints.

I can't understand why? I m still waiting to solve this milage issue.
