I take that back, they're lousy. I must have just had bad luck at the beginning. But they are quite diligent in asking how we got the number, etc. It is a pop up and it seems to be firefox specific (or at least that's what got me in) but I had to be quite vague about what it said. Then when a message on my screen popped up saying "The file you are trying to open is managed by registered scammers, please hang up if you are on the phone and close down any open windows.", instead of giving up the game, they went through the pop-up verification routine again together with phone number location verification. Also, they use logmein through lmi3.com, which doesn't have any of the usual logmein advertising or copyright information, which makes me wonder if they have a RAT version hosted on this website, so please be careful, I'm going to go and purge the VM and start again.
