Hey!
Firstly, I’m so sorry you went through that awful experience. Did the guys get caught?? Where was it you were working from, a private residence or hotel??
Ugly Mugs is free place where you can search and report dangerous people.
You can search a mobile number for any reports already up, or you can use the number you have of a dangerous person to log that for other people to see/find.
It’s helped me out a few times with people who had tried to book me.
Also, you should download an app called ClientEye, that’s a similar thing too and it’s good in that if a number calls you that’s already logged on the app as dangerous, or time waster, etc, then it has a note under the number which is calling you saying that this number has a report on the app already.
I’ve also dodged a few callers thanks to having that app. It’s easy for you to log dangerous people there too.
Hope that’s helped a little x
