Vespa — Substandard servicing of the vehicle

Our vechile with registered number of mh14 GH 5239 was serviced at auto lounge service centre last week.
First of all the commitment was to give the vechile back next day afternoon.
When we went to pick the vechile it wasn't ready .
I was told the pick up was not good so some parts need to be changed .
So that wa done still the vechile is sti the same, so not sure what wirk was done.
We had a complaint bthat the vechile gets off quite often on its own, this problem is not addressed.
The head light was changed, but the setting is in correct due tonwichbthe lights do not fall o the road, instead on the top of the trees on the road.
This is such an insane unprofessional service by vespa.
Absolutely unacceptable.
This is not the first time every time the vechile is give for the service, never the work is done in one shot .
