The problem was resolved. Due to public pressure, they gave in and returned the missing 10%, as they stated earlier. It doesn't make them seem any more legit / trustable as business partners though, since if the funds were indeed as 'super duper for sure stolen' and 'going to be returned to righteous owners'; they wouldn't/shouldn't have returned anything; neither 90%, nor 100%, no matter how much public pressure. However, the fact that they did return the funds to Janyiah201 confirms they know just as well as us that there is no way to tell if CM funds are stolen or not.
Just tried to scam over the wrong person (a Bitcointalk user)..
