Having a VAT registration means nothing. BFL is operating for over 2 years and they scammed A LOT OF PEOPLE and they are still in business. Taking the legal way against a company in the Bitcoin field needs a lot of time and the authorities which aren't familiar with how bitcoin works aren't helping the customers. HashFast failed too and nobody is in jail, AMT failed and nobody is in jail. So your VAT means 0.
Which they most definitely deserve. Those HashFail and AMT pricks need a nice stint in the big house for the shit they pulled.
Anyways, best of luck Novello. $4m is a lot of friggin' money.
