Really sorry to hear about this. Very disappointing. Hope all works out well in spite of the delay. I've always had pretty good luck selling on this type of "special interest" board, but I guess it's always a bit of a risk.
I agree, move it to the original sale post if this isn't resolved soon so we can all know who to avoid in the future. It's a shame to have to worry about that.
1) communicate the details with the moderators;
2) if they cannot resolve the matter to your satisfaction, request that they re-open the original thread (I'm assuming that it is closed) and allow you to post the details of the problem to that thread.
I might suggest that the moderators/Sean/Council consider making this approach a policy.
It is the lack of communication that is the concern - delays happen for a myriad of good and bad reasons.

First, sorry to hear this. Rainphot's post, too. That shouldn't happen.
However, if you make this public you need to identify the seller. To warn others. To give him or her a chance to respond or make things right. Most importantly, because if you don't name the problematic seller, every past and present APUG seller becomes a suspect. This makes some people scared to buy anything. It creates a sense of insecurity about the classifieds. It isn't fair to the vast majority of people who sell and buy here, honestly and happily.
one thing I would like to add, it seems to me that it would be a good idea for a seller to have his telephone available in some kind of fashion, that way communication issue should go away. I do not think feedback wars and he said/ she said approach is going to work out good.
