Need to do back ground checks on you staff

I had a crazy experience with a ADT driver today no number plates on vehicle but car number is 46730. This driver was driving like het was drunk of on drugs in and out of lanes so I when past as I have my wife and 2 children in car I drove past saying something to my wife about his driving this seems to set him off . I kept driving home he kept following me whit his high beams on at one point he over took me screaming at me as he passed. I don't think unstable men should be driving around armed acting this way and be working for a big security company like ADT. I called ADT so tell them what happened and as for the cars number plate to make a police report but I was told I would get a call back hours ago and am still waiting. I will wait hoping to get a call back if not I will go and home the police can do something about this guy with no number plate and only his car number.ADT you need to do better you are a security company you and the people working for you should make people feel safe not this
