Worst and product of Honda Unicorn

Hi,
This is JayaPrakash from Salem (Tamilnadu). I have purchased Honda Unicorn-150 from Thriveni Honda, Salem, Tamil Nadu on 25th Oct'17. I am very much disappointed about the vehicle performance and facing problems from the day of purchase. The Honda symbol was missing in the odo meter area from taken the new vehicle delivery( Laterally its fixed under paid basis) , which is being followed by the below mentioned complaints.
1) High engine vibration @5000rpm which was noticed at the time of new vehicle delivery. Same was communicated to MrVignesh (SC) for which he informed that it will get reduced after driving few kms so I believed his words and waited for the 1st service. But the complaint was still present and got increased. This was communicated during the 1st service but was not attended and rectified and I had brought this to the notice of customer care during their feedback call for which I did not get any response from their side. Please let me know what is purpose of taking the feedback from customers??
2) Same complaint persisted during the 2nd service. The complaint was attended but the engine vibration got increased and is being noticed at 4600rpm.
3) Iam getting a continuous abnormal noise from the chain and its frequently its getting removed. This complaint was also attended but still Iam facing this issue after running 300kms.
4) Stability is very poor @ all speed.
I have totally lost confidence on the service dealer and I don't want any personnel from dealer side to attend my vehicle as I feel they do not have technical knowledge to rectify the complaints. Hence, would request a qualified technical person from Honda to visit and rectify the complaints faced by me in my vehicle as I'm not getting proper service from the dealer side. Also please note that I am a HONDA customer from past 30yrs and I still believe in the quality of this product and service.
