the Winding Up order only applies to the fake UK company Decode used as a front, the bad guys and their bank accounts are in Riga and I don't suppose the Insolvency Service has told their Latvian counterparts.
The press release for the winding up is

The main web site shown in above is now renamed to the "US" version just found, the "Malaga" site is still running and linked to the US site, the Russian site shown is still running as before and there's a Latvian site that isn't even on the list. But the German site is gone.
However, the other bad guys here are at Visa and Mastercard. If they genuinely haven't spotted a problem with the number of refund claims then there is something seriously wrong with their audit procedures. If an amateur like me can track down an office and flat in Riga, university records and hobbies of some of the people involved and even a Latvian mobile phone number how come the brains of world finance can't see something wrong? Then again, how did the world economy get into it's current state...?
Anyway, back to the new US site. The London contact number is allocated to a specialist company called
Magrathea Telecommunications Limited (Douglas Adams fans presumably) who provide business users with divertable phone lines - so it could be anywhere.
