I'm not altogether clear as to whom you lay the finger of blame here...whether you are blaming the government, the liquidised company, or the official receiver.
If the defunct company have gone into administration, as you seem to suggest, then the official receiver will be responsible for selling off the assets in order to clear any outstanding debts in the first instance, and the "vague promise" of any compensation which you allege is due to you becomes null and void if indeed there is no money left in the "kitty".
It is a very poor state of affairs, I know, and it is of no help to you in these circumstances - indeed I sympathise with you and your current situation - but thousands of other able-bodied and highly competent workpeople are suffering the same plight in this unprecedented downtown in the global economy and I appreciate it may be hard for you to be on the receiving end of it. But there is little anyone can do except to advise you to take what is now on offer to you and try to re-enter the jobs market yourself.
From my reading of your post I cannot say that your former employers have acted with any criminal intent.
