A couple of years ago i had to leave my golf pirelli with kettering vw for some warranty issues, what i didnt tell that is the car had full telematics. I caught them when i logged into the car's history practically taking the car out for a thrash, i mean within 2 minutes of starting the car it was doing 110mph+ down a dual carriageway! thats 1 example, and i had all this info in black and white!.
When i went in to confront them i obviously asked to speak to the service manager, you should have seen his face it was him that was the culprit! Without going into the outcome, i have now lost all trust with dealerships, now at least when i take my car in i now have to warn them about what i have on the car.
