Modern Vespa

I've just bought this new 13' Model Piaggio Fly 125 3v.
After using it 1 month, my piaggio let me down, they tried to fix for 3 times. Nothing has changed, just after 2-3 days of working, it keeps not to start.

i have no idea how to fix this problem.

Just send a message to "Piaggio Contacts form" and they send me this message automatically "Talk to local shop". the problem is the local shop tried for 3 times, and they have no idea i think...

It seems odd to me (though maybe there's something new about the Fly that I am not aware of yet) that the starter keeps spinning even without your finger on the starter button.

what happens if you keep holding it? I know that even on my GTS, I generally have to hold the starter button for more than the fraction of a second that you seem to be pressing it.
