On 23rd December 2021 at about 2pm (edited to 1pm'ish actual time as the clock had not been adjusted) I was unfortunate enough to experience illegal and dangerous driving by one of your employees in your branded van KM57 RPZ near Basingstoke. Travelling at the speed limit of 50mph in the appropriate lane approaching a roundabout, your driver appeared at high speed behind me, I would estimate 70mph, and then when close behind me swung into the nearside lane to undertake me, before then pulling immediately back in front of me and braking. I pulled alongside the van at the roundabout as the lights had changed to red, and the driver put his window down and proceeded to complain (without any cause whatsoever) about my driving and suggested I get out of my car which I felt to be threatening behaviour. I locked my vehicle internally and fortunately was able to drive away when the lights changed. I am surprised that your business employ such people, who not only drive illegally and dangerously in your company vehicles, but then also behave appallingly to members of the public, all while presumably being on company business and representing your company.
