You got the point, they had no motivation to do so.
Oh man. If that's really the case, I'm sorry. I tried to warn people with this warning post but a lot of money ended in this crowdsale. I'm not sure if Rassah could help you by selling your shares though. As far as I know, they are not traded in any exchanges so unless you find someone to buy your stake in the open market, you probably won't have much luck selling shares for bitcoin because it seems like there is no upcoming platform to sell shares.

What Mycelium could do, is go out of their way and make an exception by issuing you a refund, but that's really not their responsibility anymore. You accepted an agreement when putting money with them and now all you're left with is a colored coin and a broken promise.
 
Even trying to fight this legally would be a hustle. I'm not saying that Mycelium's crowdfunding operation was necessarily illegal but they most certainly did everything they could so that they'd have minimum obligations to "investors" by bulletproofing themselves from courts in countries where potential "investors" would be in. They purposefully picked countries with loose laws on securities and companies as well.
