Reckless and Dangerous Driving

First time I have ever reported bad driving. We were doing 120 km/hr about 1 hour before Lainsburg. A Badela bus overtook us at around 140 km/hr, and then another 5 vehicles on a blind rise.Nearly caused a huge accident, it was terrifying. I called the number on their website and the incredibly rude woman said I was lying because 'their busses can't go above 100' When I asked if she were the Manager she hung up on me. If you value your safety do not us this bus service.
