Well, I wasn't planning on writing about my situation, but it seems like it might help.

In January, I asked for a refund for my December batch order. Last week I got a hand-written check (after an insane amount of back and forth). I took it to the nearest Bank of America branch, and I wasn't able to deposit it because they needed to speak to Cointerra on the phone. Of course, no one answers their phone.

I wonder exactly how bad the situation is, and to what extent this conduct is criminal in nature.

My thoughts on the matter are as follows:
1) If Cointerra is running an criminal scam, then they already have contingency plans in place to deal with any legal complications. Still, since they are working within a particular system (banking, legal), we can prevent that system from working in their favour. We can at least stop them from doing this to more people.
2) If Cointerra is just plain incompetent, then it is of utmost urgency to document as many details about the case as possible, and to present that information to the relevant authorities, because if they do go bankrupt, they may have little to none of their own records available to help resolve claims, and you'll want to be first in line to collect on yours.
3) If Cointerra is acting in good faith and has run up against a temporary but legitimate snag, then going through legal steps to recover funds is going to be a nuisance for both the customer and for Cointerra, and will result in wasting a percentage of the funds to be recovered, but that will be the extent of it.

So at the end of the day, given how bad things are already, there is absolutely no reasonable downside to filing very detailed reports to the relevant authorities, and pursuing all legal means available.

Obviously a lawyer or two is going to be necessary. If anyone can refer me to a good criminal lawyer, and a good debt collection lawyer, that'd be very helpful. For this particular case, it would seem that both specialities are needed. I would like to gain information on what criminal charges might apply to these activities, as well as the relationship with Terramine Hosting/CloudHashing, and, of course, I need to recover my funds.

I'm obviously angry. But to those of you who want to come to the forums to vent, and publicly threaten legal action, save your energy and instead just take action instead. Don't bluff. You have a lot to lose.
