It's pretty shocking reading on a Finnish aviation forum. These guys a capable of all sorts of crap, including threatening with violence... They're only wanting to rob young people desperate to get a job.
"Customer service" number costs you 3€/minute over normal rate, so does "booking the tickets"! 180€/hour? Pretty good going if someone happens to call, I'm sure they can put that person on hold for a moment or two...
I agree with FINpilot. Stay well away.
