If the company has gone into liquidation, it is highly likely that the owners of this company has no funds or had hidden it somewhere safe. So legally you cannot do anything unless the court decides to sell their properties and pay out the money to the investors. That's how it ideally happens.

If you know the registered address of this company, you can file a lawsuit against them and put up your demand in a legal way. It is better if you can speak to a qualified lawyer.
