Great loss in Buying Jupiter Grande

Great loss in Buying Jupiter Grande

Bought a new TVS Grande on 2nd April from the showroom. Now I have completed 3500 running with 2 free services done. The 2 ND service was on 30-05-2019. (note- while servicing was done I complained about my mileage issues which come round 36 to 38 km per litre, which is same till now no rectification to that. Secondly, the bike starts automatically stop in between the road whenever the bike gets slow, it may be in traffic, or humps or near any turning, which was somehow rectified. Meanwhile, Bhubaneswar showroom technician and one of executive informed me that there is a problem with the compressor and they have ordered a new part which will be fitted in next 15 day.
Now the question comes,
How come a new vehicle which is bought just 2month ago have Compressors problem?
And now, yesterday (I. E. 7th June 2019, after 6 days of 2nd servicing, while I was returning from Cuttack, on the mid of the road the bike automatically stop down and the bike did start after that. After severing kick, there was a huge sound and I have to walk down with my bike to a nearby garage to Check if any problem. Meanwhile, I have an all to Bhubaneswar, TVS showroom person they said me to bring the bike to the showroom, after several calls and waiting for more than 3hrs, TVS Rsa person came and pick my bike to the showroom a handover slip to me. When asked to them, the reply was its just a minor problem, will take to the showroom, open the bike and check as the kick start or self-start is accepting by bike, may have some compressor problem or engine valve problem or some other issue.

I have a question now, When people like us buy a bike for our use and within 2 months and after 2nd service there is this type of problem, How can someone be reliable to buy TSV motorbike and how can I trust these service also have open my engine and may have done some small 3and they will hand over to me and in coming future it will again show the problem I am going to be suffering for all the time and have to pay for this particular defective piece of bike which has been giving by TVS Showroom rest of my time.
