Is there any way I can compensated for what happened here? Can I file a lawsuit?

You should ask a lawyer about starting a cl action law suit. This makes the lawyer much money and teaches that bad old company to make the image on their label closer to reality. Of course you probably got what you paid for - the bag should say something about sold by weight not volume like it does on breakfast cereal. But you can indeed bring a law suit against anyone for anything. Winning is another thing.
