Reality: bithub.im and BestChange have not been able to resolve the situation with payments for about two weeks, in addition, BestChange removes negative reviews on its website, saying that these reviews are bogus. BestChange is running a signature campaign on the forum so I doubt any of the DTs will create a flag or leave a red feedback.
What do you want them to do? Pay up everyone who makes a claim on bithub.im's behalf, minus carrying out any full depth investigation?
As far as I can see, BestChange is tied up to how fast bithub.im can work on solving the issue.
The victims didn't deposit any money on Bestchange and even if they did, such Issues don't get worked on overnight.
The answer they gave is pretty much reasonable for now. Incidents happen. Just give them sometime before you start blaming DT members for not sending them negative feedback. I have tried to look through the accusation, but I haven't seen anywhere they said they don't want to solve the problem.
