Bajaj Auto — pulsar 125 / noise coming too high at the time of running

Address:

1/132, 5th street, MGR Nagar, Tiruvannamalai, Tamil Nadu, 604202

I purchased a pulsar 125 bike by cash and carry rs-82240/- at the date of 17th october 2019. From the date of purchase still now i have an very big problem in my bike i told several times at the showroom they said after first service it will clear automatically. But after first service it will start very noise like a tractor. I submitted my bike at the showroom after first service to clear that compliant four times. Each and every time they said it is company defect what can i do like that. But money is mine so i need to solve this problem by giving a new bike. Or refund my amount other wise i am disided to raise a complaint against bajaj at consumer court.
