What the hell are you talking about?  How would they publicly contact all their customers?  Are you expecting them to make all their customer contact information public?  Are you expecting them to give you copies of all of their correspondence with all of their customers?

What in their behaviour so far has indicated any of this?  I understand you are jaded.  Most Bitcoin companies are fly by night operators and many of them are outright scams.  It looks like you personally may have scars in this area.  Give them a chance?

Again what the hell are you asking for here?  You want them to make all their refund transaction public to satisfy your curiosity?  Is this to be done against their customers wills?  I and others who want to will make our transactions public.  It would be WRONG to make all of them public against the wishes of their customers who do not want their transactions public.

This is also a customer privacy issue.  Some of their customers may not want the address on their coins to be publicly known.  It would be WRONG to do this without their customer's permission.
