I am sorry to hear about your loss. The whole situation is extremely unfortunate. Unfortunately "LE" around the world does not care for privacy. In fact, they put financial privacy on the same scale as money laundering. If you lost coins in CM, the best lesson you can take is that you should not trust a centralized service. This is a good example that centralized services causing loss for users is not always an exchange. If I were you, I would consider the coins to be gone forever. Even if you were able to make a sound case for your using the service for privacy, it would be quite a hard and expensive battle to win in court. I'm not saying that you should not fight, but it will be a tough one.
