[Resolved]  Volkswagen India — recurring issue of vibration while braking

Address:

Ernakulam, Kerala, 686692

This is regarding a complaint i'm facing with my vento highline tsi vehicle which i bought on 2016.
Before the vehicle crossed 1500kms mark this complaint arose. Vibration on the entire vehicle while braking. I mentioned this clearly at my first checkup itself and experimental works were carried out by the service engineers rotor polishing (Which was paid service even though my vehicle didn't do 1500 kms even). Again after few months this complaint arose again this time little more advanced tests, result was replacement of hub, bearing assembly under warranty. They didn't find anything with rotor (God knows whether they inspected it or not) adding to what they found out replacement of brake pads were also done (Which was also a paid service). Now again after all these services vibration is still there. Now the scientists at the showroom are telling me to replace the rotor for which i should pay.
From 2016 till, 2018 till date these so called scientists are experimenting with my vehicle asking me to pay for whatever things need to be replaced. After so many services i have lost faith in giving money for all these repairs. Now on what faith should i spend money on this issue. I asked to replace it under warranty since it's an issue since 2016. I don't mind spending more on this if this is gonna be a final experiment. I asked for a guarantee in writing from the so called scientists. Even they are not confident enough that this is going to get fixed by this replacement.
My vehicle is not your scientist playground and my hard earned money is not for your experiments. I agree if it was some mechatronics error or electronic fault. This is mechanical complaint which should be rectified in a service or two, not like this series of experiments.
Pathetic experience with the service engineers and service provided.
Another worst part is that, for me i took vehicle from cochin kerala and did initial checkup and first service at cochin itself that is evm volkswagen cochin, they have the service history with them. When i told them that i can't bring my vehicle every time to cochin for this issue, they told me to get to any convenient showroom nearby, so i went to evm volkswagen perumbavoor (Both belong to same owner/dealer). Now the thing is perumbavoor guys can't look into service details at cochin and they can't follow up with the complaints i registered at cochin that's what they informed me. I do have proof for all these things since i refused to have telephone conversation.
Really pathetic service volkswagen...
