This is just to post that CampBX did finally retrieve my bitcoin today.
I want to say thank you to them for doing so, but it's hard to after not getting any response on my support ticket until I PMed someone on this forum that appears to be associated with CampBX.
And then they just blamed the problem on me!  I believe it was faulty programming in their system.
Then after waiting more than the requested two weeks with nothing happening, I finally PMed again.
Then I got an email saying that they were running five days behind schedule.  Oh, well that explains why I'd been waiting a month at that point!
I've been waiting patiently and the five days must have past now.  Apparently, they are not using the Gregorian calendar.

As long as nothing goes wrong, their exchange works okay.
But I'd rather use an exchange that has actual customer support.
Good luck to anyone that uses CampBX.
