A "strike off action" means that they have not filled in their annual accounts.

But have not had any luck.

Goggle show up lots of companies are registered at 14 Hanover Street. So it looks like a company selling "off the shelf company registrations" is who is really there. The Company report from business intelligence company I use might give you more leads to follow

Here is a custom search that might turn up something.

I have an account at Intersango and so this thread caught my eye. I used them when they first opened as they where the only place you could get Bitcon back then. I logged in OK and found I had left 3 BTC in my account (small change at that time worth £12) so I have made a request for my 3 BTC.

Think of England as a pirate ship off the coast of Europe as far as finance is concerned so unless fraud can be proved rather than just sloppy business I would expect the police to get involved. In which case it would be a civil matter and it would be difficult to recover any money. If the company is forced into liquidation a Receiver would be appointed. They would sell any assets and the tax man would get first bit of the cherry. But I'm not a Lawyer. I can buy the report for you if you like.

Hope this is of some help.
