Hero Motocorp — Hero scooty duet, vibration problem

Exactly... I don't understand why there is a difference of opinions at different service centres of hero. I don't use the hero duet VX much, its mileage is poor, handling not good, kicker is a huge problem, with repeated requests at the service center to rectify & they seem to have some what corrected it, but the major problem off vibration is very evident and there are two types of vibration which I have observed 1S vibration which happens when the vehicle is idle after it's been started, there is a kind of sound which seems to be due to improper alignment of the internal parts, this I've notified 2D mechanic but he gives me an absurd response by saying that it will be alright if ride for more kms( I always thought that the engine and internal parts gets worn out if you use it more than required but here they are suggesting me that I make more and more use of it to get rid of this sound & shaking) & the second one is the vibration which happens the moment you cross 60 km per hour. I don't know who is going to look into to all these things but it's a pathetic product by hero.
