Negligence

I had my car serviced at Autohaus Centurion on the 28th of March 2019, just before my long distance travel. During my trip I started to smell burning oil then I pull over at the nearest garage, only to discover the oil cap after the service was not replace and the engine was full of oil. I then reported the incident to the workshop manager first thing Saturday morning. when I took the car back on Monday, the least I expected was for him to be present to at least apologize for the inconvenience caused. Being in the service industry that is the least we could do, to ensure that the customer feels valued. Unfortunately Autohaus made me feel like it was all my fault. It’s really been a horrific experience and great danger to my life and my family as we were driving a car with oil cap open and oil liking due to their negligence on my car. To be honest I don’t feel safe driving my car after what happened because I don’t know what other damages has caused. I need to understand how VW plan on resolving this ethically. And I also want my car to undergo an 80 point check for faults and any faults that might have caused by this incident.
