India Yamaha Motor review: regarding poor services - walters yamaha, medavakkam, chennai

Regarding poor services of walters yamaha chennai
Im moving around this show room from 6 months they are keep on changing the parts but problem has not yet corrected.
I bought fascino in 2016 after that I noticed wobbling at handle site and I asked them to clear. After 2 services the problm has not been corrected they asked to me to change front disc, then front tyre, then handle fork problem. Yes everythg done but problem remained the same. Later they told problm was with back tyre they replaced back tyre the problm is same, for this the service manager of 4 show rooms named mr stalin mobile no - 9677175321 attended but problm is same.
Yestersay I went to show room to inform to their md regarding their worst services but they told that md wil not speak to customers. I was waiting from 6.45pm to 8.30pm. The manager of that show room mr venu mobile no - 9677715330 have closed service center and asked me to sit outside the show room. Yes I did I sat infront of the show room on the road finally they have called the police to vacate that place.

To whom we should complaint after their worst services
Is this the respect u give to the customer?
How can they change all parts without knowing what exactly the problem is?
Is your company has such protocols that if customer is not satisfied they should send out and make them not to come for any service again?
