Honda 2 Wheelers India — honda unicorn bike

I had brought unicorn 150 on 03/09/2018. But from 6 month i am facing problem within a 3 week had problem in gear between 4th and 5th. During the service i had informed and they did something and said the problem is resolved still after service i had face the problem.in the month of december 10 i was riding the while riding the bike the bike stopped completly the he highway which risk my life also. Then i went to the service station then they changed and cleaned carborator and tapet the rubber was also changed. And they charged me in second service and i had the same problem after second service. The bike used to stop and i had gone to pilot honda chembur and they did something and said now problem is resolved. But again the same problem started the bike used to stop in between riding. Again i went to pilot i have problem in engine there is lot of sound in engine. I have shown to pilot honda chembur 3 service over but yet not the problem resolved. I have spent lot of money 3 service warranty over. Now there is lot of sound.. Now while riding the bike i feel uncomfortable because again i feel there is problem... Because the oil is leaking form engine part.
