[Resolved]  Volkswagen India — ABS sensor failure

As per the complaint filed by myself on 12/10/2019 to volkswagen customer care with case number ccr192589 regarding abs sensor failure of my volkswagen polo, the service centre (Evmvolkswagenumayanalloor, kollam, kerala) has resolved the issue, but after few weeks the same issue came up again and i have abs sensor warning on my vehicle throughout the drive.
I have approached the same service centre again to resolve the issue and they were not even ready to listen to me and not ready to resolve my issue. Right now they are demanding to pay the full amount that will cost for abs sensor replacement for admitting the vehicle into the workshop even though my vehicle is on extended warranty. Right now vehicle is in my garage and is not using regularly because of this issue.
Even though the service centre claims that they had replaced the sensors during last service i don't believe that because how could a new sensor fail within few kilometers (Vehicle had done only 975 kms till date after third service) and even i didn't get any proof that they had changed the sensors. Sensor warning came up again on last of november 2019 and i approached the service centre by the first of december 2019 after that i was out of station and had no time to follow-up till now.
I am extremely disappointed with the bad experience and the misbehaviour i have faced from your service people. I look forward to your reply and a resolution to my problem.
