Found this British scamming company calling themselves Equita, their website is www.equita.co.uk and telephone number is 01604628360
Update: YouTube videos confirm mail fraud scam.
Can you elaborate what kind of scam they run?
It’s a mail fraud scam, they call you up claiming to be acting on behalf of civil matters as an enforcement agency, yet when asked will refuse to provide real documentation, and insist they’re acting with lawful warrants that are not signed by any judge or even a real person. Also, their warrants look nothing like a real warrant.
