The best solution is for us to all pony up and hire a lawyer to get our money back. But that's expensive.
So for now, we should probably contact the Ontario California Chamber of Commerce about what has happened.
When you contact these guys, be sure to state that you had a contract for one or two years of service, and that you have already paid in full. And that now, the company is disappearing, and you are seeking a refund for the remaining time of service. Or something to that effect.
I'm not a lawyer.
Here's the Ontario California Chamber of Commerce web site:

If anyone has better ideas, post here! I'd be happy just to have the service back, personally.
