Has the FeeFighters Samurai gateway been shuttered?

I spent several days setting up the Samurai payment gateway with a new product I'm building. I ran into a mysterious error, so I submitted a help request. No response for a week now. Their phone number isn't working, no response on twitter, no response over email.

Is anyone else using Samurai? The product looks excellent, but this support is abysmal. I see they were acquired by Groupon on 3/23, perhaps Groupon is dropping the gateway portion?
