Re: I am just amazed by the original "IT contractor" doing that.
Er.... Never heard of the scumbags who setup a company create havoc and then liquidate it before the shite hits the fans and then they setup another company (often with an almost identical name) and ... wrinse/repeat all the way to the bank.
Now try taking legal action against an entity that no longer exists. What answer do you think that your £300/hour is going to get?
