If the company went bankrupt the only way to get your money back is to present (and deposit) a document where you ask to submit your credit to the passive of the procedure in order to be restored. Obviously, this should be valuated by a responsible party which, in this case, whoul be the "curator" of the procedure itself.
Apart from this, from a criminal law point of view, you could also present a fraud report in order to be defended in both areas.
I would be pleased to explain you more, if that would be necessary.
