Poor customer service across the board

I bought a vehicle from VW Woodmead. The vehicle appeared to be fine and had no issue's. I did not notice the signs of accident damage initially but once I had the vehicle and in better lighting then I realized that the vehicle may have been in an accident. I went back to the dealership and enquired about this but I was brushed off and rather told that it may be nothing however almost two years later and the paint seems to be fading in the exact spot where I suspected repairs were done and the signs of repair work are becoming more apparent. Additionally the vehicle loses power randomly and I can not use electronics at the same time, for example, having the radio on and opening a window or switching the A/C on, even using the indicator makes the car lose power. This issue comes and goes at random. I have taken this issue to the dealership and was informed that it was sorted out. I even purchased a new battery after that because of the issue persisting, it worked for a while and a few months later the issue came back. Other consumers should be aware before making big financial decisions.
