A rendering of Life at Sea Cruises' MV Lara
  • Life at Sea Cruises canceled its three-year expedition after failing to secure an appropriate ship.
  • Some passengers spent their life savings and sold their homes to pay for the voyage, a report said.
  • Now, a group of passengers say they still haven't seen their money back.

A group of passengers who were supposed to go on a three-year voyage around the world with Life at Sea Cruises before it was canceled two weeks before its departure is now demanding a criminal probe into the company as customers say they're desperately trying to claw back $16 million in refunds.
