Hero Motocorp — poor and worst service ever.

Address:

Dharwad, Karnataka, 580031

Everytime i give my hero pleasure to service, they cost me a lot, and everytime the work is literally useless, i'm tired of this, they won't even respond if i say them, that i am going to complain about them, please take serious actions towards them.
Everytime i give them my vehicle to get serviced, i explain them in details what all should be done, but still, i'm very very very angry... I request you please, take serious actions against them,
I am a middle class poor guy, i can't spend all the money on the vehicle, i'm really upset, please take serious actions against them.
