Honda 2 Wheelers India — no satisfaction of vehicle usage

I bought two wheeler sp shine 125cc 2018 model, reg no : tno5 bq 3238 from jsp honda dealers at chennai annan agar on february 2018. On same day i had a test drive myself before delivery i found there is handle bar bend while i driving feel uncomfortable but delivery person said it will like that only so taken delivery late nite 9pm. After few days i feel my right arm shoulder getting pain regularly then i consulted physician finally we came to know because of vehicle handle bar problem so immediately taken back to showroom after long observation they changed to new handle bar but after that constantly i am getting problems like rare wheel tyre air leak, back break not comfortable while applying, mileage drop, noise on applying first gear, and also handle bar in same condition like earlier. Last 2 days back while on driving suddenly vehicle got switchef off automatically then immediately i self started moved and released clutch immediately vehicle raised in opposite direction and myself fall down on highways road by luckly i am not injured much but vehicle rare lights broken. Finally i decided to return back vehicle to vendor because by daily facing many problems for this vehicle. Now vehicle at jsp honda service centre thirumangalam, chennai. Thanks to honda team.
