Hero Motocorp — Vibration on vehicle

Dear Executive,
This is to inform you that I, Srimanta Ganguly, have purchased a Pleasure + (VX) on 10th May 2021 from M/S Siddhi Sree Vinayaka Motrs (Adds. - Srinivasa Complex, no. 5-6-148/3, Ramagundam, Peddapally, Telangana, 505215, statecode-36, contact no. - [protected]). The travelled distance of my vehicle is approx. 5400 km and have availed last servicing on 28.01.2022 servicing from the above mentioned dealer. Also, apart from the servicing I took my vehicle at least 15 times to the service centre to rectify my vehicle problem persisting before the first servicing but with deep grievance I am to acknowledge that neither my problem was solved nor got any proper dealings. Moreover, during my 2nd servicing I was informed that gear box bearing would be replaced as it got damage. With height of surprise to me, I was to change the bearing with my cost but how could within 07 months of purchase bearing be damaged.
Please take a look of my vehicle particulars for your ready reference-
1. Registration no. - TS 22F 6364
2. Chassis no. – MBLJFN067MGD02549
3. Engine no. – JF16EJMGD12249
4. Manufacturing date -04/2021
This is for your kind information that my working nature is of travelling type and without my vehicle it is very tough to carry out my job. So, it is my request to take a proper step to restore my vehicle condition.
Thank you.
